Fungus or Ich? (Disease Dilemma)
Hi Mr. Fenner,
<Scott F. in today!>
Thank you for such a fabulous informative site. I've been reading and reading
and am a bit overwhelmed.
<It can be a bit intense. Do read and explore at your own enjoyable pace!>
I'm new to this hobby (17 months & counting) with
no "big" problems until now. I've noticed a couple of white spots on my Regal
Tang, some looking like cotton fluffs!? Is this ICH? My other fishes look OK
(2 Chromis, 2 ocellaris). I have a 60 gal reef tank with 100 lbs. LR &
2" of LS.
<Well, it's hard to be 100% without a picture. If it is ich, the spots look more
like grains of salt...Since you're talking about "tufts", I'm thinking that this
might be a fungal disease that you're looking at. Do read up on fungal diseases
here on the WWM site to confirm.>
One of the postings on your site stated they had a reef tank with LR & LS and
also a light case of Ich and you suggested get some Lysmata shrimp and/or
cleaner gobies. Can I also try this for my tank or would you recommend catching
the tang and putting him into a hospital tank with medication?
<I'd certainly try to exhaust "biological" remedies before resorting to meds, so
do try this. However, fungal diseases generally require antibiotics and very
clean water conditions in order to affect a successful cure. I'd try the
cleaners first, but be prepared to intervene medically if this proves to be
unsuccessful.>
Also which cleaner gobies should I get if there are several?
<I'd get the classic "Neon Goby", commonly found at tropical fish stores.>
I can't imagine how this tang got ICH, he's been in the tank along with the
Chromis & Ocellaris for approx. 1 1/2 years and no problems. NO new
introductions to the tank in quite a while!
Thank you for your help.
Marilyn
<Well, Marilyn- it really sounds like this may not be ich. Fungal infections can
occur regardless of whether or not new fishes are introduced. They can occur as
a result of wounds that the fish incurs from abrasions, etc. Good water quality
and medical intervention are usually all that is needed to lick them! Good luck
in your battle! Regards, Scott F>
Learning From His Mistakes!
I have never had a fish tank in my life. When I started working at a pet
store two years ago, I could have cared less about fish. Of course, the more I
was around them, the more I started to think, "I could set up a tank".
<That's how the addiction starts!>
I decided to make my first tank a marine tank. I only chose to do this because
the people that I worked with have had marine tanks most of their lives. I got
a 29 gallon tank to start out with. I put in live sand and about 30 pounds of
live rock. I bought an Emperor 400 knowing that this would cycle the tank
plenty. I put in the water an salt and water conditioners. I let the tank
cycle for at least three weeks. I finally bought a blue yellow tailed damsel
and a domino damsel. I also soon after bought some turbo snails, a cleaner
shrimp, blue legged hermit crabs, and a peppermint shrimp. The tank was fine
for at least a month. I then went and bought a Percula Clown, a Regal Blue
Tang, and a Tan Sailfin.
<Wow! A LOT of fish for a 29 gallon tank...A much larger tank should be in the
very near future with a stocking list like that!>
After about a week, I noticed that some of the fish looked like they had ich.
<Uh-Oh...Do remember to quarantine all new fishes for at least 2-3 weeks before
placing them in your display tank. this gives you a chance to catch diseases
before they get into your display tank...>
I went to the store where I work and was told to get some ich guard. I bought
some medicine called QUICK Cure. I applied the correct dosage daily as
instructed and waited to see what happened. Slowly, every one of my fish died
except for the cheapest one, the yellow tailed blue damsel.
<Sorry to hear that...>
I continued to add the ich guard for a few weeks and just let the tank cycle and
hopefully, the ich would go away and the water would go back to normal. The
damsel never showed any spots so I assumed that my water was safe for fish
again. I went out and bought another Percula clown and a saddle back clown. It
has been two days now and the Percula is starting to get white spots and
sometimes seems to twitch. Do I need to completely tear down my tank and start
over or do you have any suggestions on how to fix my problem? First Time Trent
<Well, Trent, don't get too discouraged about this first time disaster. Yes, it
may very well have been avoided with a few procedural changes on your part, but
your intentions were good, and you did learn some valuable lessons that will
save you more heartache (and fish!) in the future. Tragic though this was, the
fishes will not have died in vain if you apply what you learned. First, plan a
sensible stocking plan that will work in the size tank that you have. Quarantine
all new fishes prior to introduction into the display tank. Next, stock
slowly...Give the nitrifying bacteria in your system a chance to adjust to the
increasing bioload of your system. There's no need to rush things. If ich or
other illness should manifest itself in your tank, you should remember to treat
the sick fish in a separate aquarium, which affords you maximum control. Ich can
easily be defeated in this manner, and you can leave the display tank running
"fallow", without fishes, for at least a month, which will help "crash" the
disease's causative protozoa population for lack of host fishes. Meanwhile,
conduct normal water changes and other maintenance in the fishless tank. When
you repatriate your newly-cured fishes into the display, they'll have a much
better chance of resisting any remaining protozoa. Finally, arm yourself with a
good basic book on marine aquarium keeping, such as Michael Paletta's "The New
Marine Aquarium", and continue to study the vast amount of material we have here
on the WWM site regarding marine aquarium husbandry. With a little education and
some persistence, you'll join the ranks of successful marine hobbyists sooner
than you know! Feel free to contact us again any time! Good luck! Regards, Scott

Urgent: Need help to cure diseases 10/20/04
Dear Mr. Anthony Calfo, sorry this is a long letter, but I need your help.
<I have read your query below at length - and I'm not sure where to begin. You
clearly have taken the time to read about the necessary parameters of
quarantine... but you categorically ignored them :( Your eagerness and
impatience has cost considerable lives here. There is no other way to say it, I
am sorry to say. It disappoints me and makes me sad to hear so many stories like
this by intelligent people that choose to ignore the critical need for QT at the
expense of the beautiful living creatures. My advice here is to remove all sick
fish to an appropriately sized QT tank, and follow proper QT procedure: 4 weeks
minimum, daily water changes, etc. The display tank will run fallow in the
meantime. You can read some more current information on Oodinium and QT/disease
in recent articles by Steven Pro on reefkeeping.com e-zine. Please do take the
time to read and follow basic QT and disease treatment protocol. Best of luck.
Anthony>
Recently I have a very serious problem. My whole fish are attack by Oodinium.
Let me tell you the story :
-The system are very stable and all the fish are very healthy until at Sept 21 I
buy a new emperor angel, I QT it for few days with copper dip. Then because I
receive a new shipment (queen angel) that I ever ask to you, I release the
emperor to the main tank (no sign of diseases) and use the QT for the queen. And
as I told you the queen wasn't eat until it dead because of starvation (not
strike by diseases) in about 10 days in QT tank.
- In the meantime, after about few days in the main tank the emperor shown a
diseases, but I'm sure it wasn't Oodinium because Oodinium will give a powdery
shown if seeing from side of the body, it just like a whitish spot/mark on the
entire body of the emperor. For the first time, I don't think it gives bad
effect, since the emperor is still eating well and not rub to the rock and not
shown a rapid breathing. The rest of the fish are also not shown being infected
and still healthy. This condition happen for about a week.
- Until about a week the whole tank are infected with disease, but not same with
the emperor only my majestic strike with the same diseases like the emperor, the
other fish are strike with Oodinium. I let this condition happen for few days,
because' I wait until weekend (because workday I don't have time to change the
water.) Firstly, I don't pay too much of attention about this diseases since
they are sometimes also strike with Oodinium several times before this tragedy,
I think it was because of bad quality water when I do a 20-30 water changes, or
may be when I introduce live food, etc. But after I heat the water to 32 degree
for several days, the disease will just gone. So I think this time will also not
do much damage to my fish.
- At 9 Oct evening the majestic dead, I do 50% water changes and catch the
emperor and gave it to the LFS. At that time, all of the fish are still infected
but still shown good performance for ex., still eating well, not rapid
breathing, even though they rub but they don't rub very often. - Oct 10, I still
shot and that a picture, they still shown good performance. Oct 11 morning,
things are start to worse, my precious fish like regal and golden are start to
refuse to eat. At this time I already lost 2 of my butterfly, it was a falcula
and a copperband which already 1 year in the tank. The copperband is shown an
open bloody wound in the body. Oct 11 night, I catch the regal and the golden
and put them in the QT and did a copper medication. Even at this time both of
this fish is still not a motionless, they still hard to catch and not give a
rapid breath, they just refuse to eat.
- Oct 12 morning, the regal was dead. The golden is still survive but the
condition is getting worse. Oct 12 night, the golden was dead also.
- The rest of the fish are also infected : the juve. three spot angelfish are
strike with lymphocystis and lost it's fins very badly and also show an open
bloody wound in his body. The keyhole & the bicolor are strike with little
whitespot and give a very pale color. The cleaner fish & 3 of my clown are not
strike with this diseases. The king angel are strike with little whitespot and
still eating well. All of this fish is not moving from main tank, since I only
focus the regal and golden.
- But what makes me confuse, all of the fish that I don't move are still alive
today, in fact the three spot are getting better and the fin's are 80 % recover,
the keyhole & the bicolor are 100% recover their natural color and not strike by
diseases. Why this can happen? Did I do a wrong procedure? What will happen if
I'm not move the regal and the golden, will they survive also?
- While the condition in the main tank is getting better which prove by the
recovery of other fish, my king is shown a degradation condition, start with
refuse to eat my DIY food & Mysis shrimp but still eat pellet food greedily, but
since yesterday it refuse to eat everything. The fish is look good, no whitespot
and Oodinium, no pale color, no rapid breathing, no darting, no rubbing, just
NOT EAT. This morning I try to read in WWM, I suspect my king are strike with
internal bacteria, this is taken from WWM : "Internal bacteria infections are
often identified by symptoms; swelling, a fish that has trouble staying on the
bottom, whitish feces that float or trail off behind the fish, or lack of feces
entirely (blockage)." My king are shown whitish feces that float or trail off
behind the fish, or lack of feces entirely (blockage). Please help me to cure
this condition. What should I do? Do I need to move the fish, of let it cure
naturally? What is the medication? I don't think
antibiotic that put in the food is a way, since the fish is already reject to
eat! Please analyze my problem & gives the solution & please save my king!!!!
Thank you very much Hengky Wijaya
Rising From The Ashes (Recovering From Disaster)
What's up?
<Not too much! Scott F. here tonight!>
My fish have become sick, cloudy eyes, slimy, spots and soars. I suspect it is
from the feeder fish I have been using lately (I live in FL. and my LFS could
not get Ghost Shrimp because the hurricanes broke the supply chain.).
<Sounds like a good possibility>
I have tried every additive they tried to sell me along with lots of water
changes.
<Water changes are good...Additives may not be useful...>
I'm down to 4 sickly non feeding fish from 12 in a week and a half. I realize I
probably can't save them. So if I decide to start over and restock, what the
deal? Are all of the crabs and starfish and snails infected along with the live
rock. Should I trash it all? This sucks! Thanks in advance. Josh
<It certainly does, Josh...But all is not lost. The symptoms that you describe
can be caused by anything from parasitic to bacterial conditions. I suppose that
removal of the sick fish to a separate tank for treatment is appropriate here.
If you are describing ich symptoms, I am a big fan of the careful application of
copper sulphate or formalin-based remedies. Follow manufacturer's instructions
to the letter when using any medication, BTW. The main tank can run "fallow",
without fishes for a month or two. The crabs and starfish are not thought to be
"carriers" of the disease, so they can remain in the tank. The "fallow" period
will allow you to deprive the causative parasites of their host fishes,
interrupting their life cycle and potentially reducing their population to an
insignificant level. Continue all regular maintenance (water changes, etc.) in
the tank during the fallow period. Don't give up! You have nowhere to go but up,
and the Crew at WWM is here for you the whole way! Do read up on the disease
FAQs for much more detail than I can go into here! Good luck! Regards, Scott F.>
Counterattacking A Disease! (If It IS A Disease)
I recently set up a 12 gallon Via Aqua reef tank and put in Catalina water,
live sand, three live rocks, and a Tongan branch. Before I put all that stuff
in, I had the tank running for about a week. I bought a cleaning crew: two
shrimp, three hermit crabs, and a blue knuckle crab. Two days later I added a
coral, a scooter blenny, a yellow clown goby (this guy is about 1 cm), and one
false Percula.
<Wow! That's a lot of bioload added really quickly after startup. Did you
monitor ammonia and nitrite during the cycling period? Did the tank actually
cycle yet?>
The false Percula only lasted about a week because it died. His cause of death
of very sudden-one day I noticed a long, white stringy matter coming out of his
exit hole, and a couple of white opaque spots on his body. The very next day he
was lying on the bottom of the sand with a open lesion on the side of his body
and I decided to take him out of his misery. ( I found it rather fast that in a
matter of hours something could eat away at it so fast.)
<Sounds horrible. Could have been caused by any number of things. Selection and
reliable source are keys. too. Sounds like it might have been parasitic in
nature, but it would be impossible to determine without a pathological exam at
this point. The need to quarantine all animals prior to being placed in the
display tank cannot be stressed enough here...>
The tank is at 77 degrees, and the hydrometer and marine test kit params are in
check.
<Ammonia and nitrite are undetectable? Do confirm this>
So, I decided to go to Petco and buy a pair of tank-raised false perculas
thinking that the one that "bit the dust" was already sick when I got him from
the LFS. I brought them home and they acclimated well. I had them for a week now
but now one of my clowns is rapidly breathing hard while sitting
atop the coral. Today he's a the bottom of the tank breathing hard.
Since my first clown died of something eating away at him, and now my new clown
is sick and breathing hard, what should I do? I don't want to start all over
with new rock, new water, etc. Can I still save him? And with what? Help, and
thanks for the advice!
Sincerely, Janet
<Well, Janet- sounds like it could be two possibilities here. The first thought
is that your tank has not "cycled", and excesses of ammonia and nitrite are
poisoning your fishes. Do test ammonia and nitrite again so that you can rule
out this as a probable cause. If the parameters do check out okay, then the
rapid breathing and lethargy displayed by the fish could be one of several
virulent parasitic illnesses. My thinking is that you may be looking at
Brooklynella, which is common to Clownfishes, and can kill quickly if not
attacked. I would remove the affected fishes to a separate tank for treatment,
using a commercial copper sulphate remedy. Follow the manufacturer's
instructions to the letter, and be sure to test for copper concentration. As far
as the display tank is concerned- you may indeed need to remove all of the
fishes and let the tank run without them for several weeks to deny the parasites
their hosts. Yes, this disease is nasty- and it could become necessary to
completely break down the tank in an extreme situation. It's that bad. Let's
hope for the best, though- and get those fishes out of the tank for treatment.
Time is of the essence. Remember to move slowly when adding new animals, but
quickly and decisively when treating diseases or correcting problems. Arm
yourself with a good basic primer on marine aquarium keeping, and go for it!
Best of luck to you! You can lick this! Regards, Scott F.>

Rapid Death of Several Fish (9/15/04)
Hey my names Brian. <Steve Allen with you tonight> I have 29 gallon fish
only aquarium with a AquaClear 300 and a Via Aqua Skimmer. There is 15 pounds
of live rock. <This tank is far too small for Yellow Tangs, which need a minimum
of 75G to grow into. It is also too small for the Maroon Clown, which grows to
5" and gets very aggressive. Guaranteed to slaughter a Percula in this size of
tank as it grows. One or a pair of Perculas is a far better choice.> The tank
has been running for about 2 months. Last month I bought a blue damsel who is
doing great. <Also likely to become a killer in this size of tank.> Two weeks a
ago I had my water tested and it was perfect. So I bought a maroon clown and a
Percula clown. <And you didn't quarantine them, right? This is why you now have
the problem you do. Please study quarantine on WWM to save yourself a repeat of
this loss.> They were great for a few days then the Percula clown turned
whitish and started swimming weird. A few hours after he died. <Sounds like
Brooklynella or Amyloodinium (marine velvet). Both very bad and very contagious.
Read about these to see if this is what you have.> Then the maroon clown who was
perfectly healthy stopped eating. <Probably has the same thing.> In the mean
time I bought a yellow tang. <Best not to buy a new fish when dealing with the
unexpected death and illness.> The tang eats great looked great until 3 days
ago. The tang started to look pale and have white spots on his body. <Small ones
like salt grains? Bad. marine Ich (Cryptocaryon) or Amyloodinium, which is even
worse.> The paleness comes <with the fish's stress level, though they turn
white at night when healthy.> and goes and so do the spots. <Ich comes and goes,
but sounds like your tank is contaminated.> I read that if his fins are erect
that it is bad. <Hmm, where did you read this?> I this true? <Quite the opposite
is true. Erect fins are a sign of vigor and clamped fins are a sign of illness.>
His fins are up 60% of the time. <Or clamped 40%, suggesting he is not well.> I
have
bubbler in the tank, can the spots just be bubbles? <Highly doubtful, especially
with one other fish dead and another ill. Bubbles are obviously spherical and
are shiny silver-white under the light. They are transient enough that on an
active fish, they come off in moments.> I have been putting stress coat
and Melafix for the clown and he is looking better. <For now. You have some sort
of parasite in your tank, and neither of these will solve your problem.> I
cannot afford a hospital tank <Yes you can. All you need is a $5 plastic
Rubbermaid container, a cheap sponge filter, an inexpensive heater of at most
100 watts, and a couple of PVC pipe fittings as hiding places. No rocks, no
sand, no decorations. You don't even need an aquarium light--the overhead lights
or a lamp will suffice.> and I heard that even if you treat fish separately the
parasites will still be in the tank. <If you leave the tank free of fish for 4-8
weeks, virtually all of the parasites will die for want of a host.>
This is my first marine set up please help because every store in my area tells
me conflicting things. <Yep. And so will the Internet. The bottom line is that
Tangs are Ich magnets, any you should not have one in your tank anyway. Too bad
somebody sold you this fish. However, the illness probably originated with the
Percula, which is why we recommend strict quarantine of all new acquisitions for
4 weeks, which is as close to a guarantee of a parasite-free tank as you can
get. Did you know that a 10G tank can be had for as little as $10 at Petco.
That's probably less than you paid for the dead Percula. This may sound harsh,
but if you can't afford a simple quarantine/hospital set-up, you can't afford to
maintain a marine aquarium. Around here, Yellow Tangs and Maroon Clowns both go
for around $30. Dying fish get expensive fast. Believe me, I know--I've lost a
couple of $100 fish. Quarantine is cheap insurance. Go to www.reefkeeping.com
and find Steven Pro's articles about ich and velvet. Learn about their life
cycle and prevention and treatment. You can even post your dilemma (or any
other) in the newbie forum at www.wetwebfotos.com and get a lot of great advice
from experienced aquarists, including Steven Pro. You can succeed, but some
fairly drastic action is needed at this point.>
Three Blind Fish- One Big Mystery!
Over the last three to four years I have had several fish go blind. One was
a Niger Trigger, one was a Heniochus and one was an Emperor Angel. Do you have
any idea what could be causing this? In each case the fish was healthy in every
other way and just became blind.
<You're sure that they are blind? This is a rather unusual phenomenon, and could
have its root cause in a number of things. My immediate two possibilities would
be environmental or nutritional. The fact that this is occurring on more than
one fish may support this theory. My first recommendation would be to review
your fishes' diet. Are you feeding them a variety of appropriate, marine-based
foods, in sufficient quantities, each and every day? All of the fishes that you
mentioned have nutritional requirements that favor marine-based food items. Do
make sure that you're using a variety of good quality frozen foods as a major
part of their diet. You may also want to enrich them with a vitamin preparation,
such as Vita Chem or Selcon. Run some environmental tests, for parameters such
as pH, ammonia, nitrite, nitrate, etc. See if you can get a handle on the water
quality in your system. Utilize aggressive protein skimming, chemical filtration
media (like activated carbon and/or Poly Filter), and regular water changes to
keep things up to par...Review those husbandry procedures and make sure to
correct any deficiencies in this area.>
Also, I have a Yellow Tang which I have had for about five years. All of a
sudden its fins are deteriorating. The caudal and dorsal fins look like they
have been nipped or bitten by another fish but after close observation, I
cannot see that any fish is causing this. Do you know what could be causing it?
Thank you in advance for your assistance.
Stephen W. DeFilippis
Wayne, IL
<Hmm...Again- the dual possibilities of nutrition and environment seem to be the
ones you should be checking out. With the tang, do try feeding it some fresh
macroalgae (such as my fave, Gracilaria) and see if this helps a bit. Keep
trying the possibilities- your fishes will let you know what the problem is.
Good luck! Regards, Scott F>
The Eye Has It (Follow Up On Eye Injury)
Thanks for the suggestion of Epsom salt. It seems slightly better but still
has a long way to go.
<Glad to hear that it's working. Keep up clean water conditions as well, and the
fish should progress nicely!>
I was wondering what I can add to this setup.
The wrasse will not allow another fish, and besides that, the crew has in the
past indicated I am maxed out. So can I add a mushroom that requires medium
light, whatever that means. If that is a good addition what type of fluorescent
bulb should I have. The one I have now came with the cover and is over a year
old and looks like it needs replacing. Or would live rock be a better addition?
<Personally, I'd start with some live rock. You'd be surprised of the many
benefits of using good quality cured live rock in your tank. Then you can add
some hardy corals, such as Mushrooms. Do consider changing the bulb or even
upgrading to PC's, which give you lots of "bang for the buck" in a small tank!
Have fun, but go slowly! Regards, Scott F>
Re: communicable diseases
hi guru folks <Hello. Steve Allen ith you tonight.>
I am so amazed with the service you provide. I did my best to find my question
among your archives but could not come to complete resolution so here we go.
I have a 72 gal tank approx. 3 mo.s old. I let it run for a good month with
little result in cycling, (I only added live sand) so I put in 5 Turbos 6 little
hermits, a big red hermit and one neon goby (over about two weeks) all seemed
fine, nitrates came up and went down. all checked out well in re to pH, temp
salinity, N indicators. after a week I added anther neon goby and a perc. All
seemed well after 10 days or so I added a Dottyback, which seemed fine for week
or so then gone, I found it being gobbled by the red hermit. <Almost certainly
died of something else and then scavenged by the hermit.> A little later the
perc had sign of fin rot, I added Melafix for salt (I have had great luck with
this in fresh water ponds) <Experience would suggest that it is not as effective
in saltwater.> The directions stated to add it straight to the system and let
it run for a week or so followed by 25% water change, well shortly after the
addition the perc went followed by the gobies. then I found the red hermit
munching a turbo (could it have been weakened by something?) <Perhaps the
Melafix or some other toxin or change in water conditions.> The LFS later told
me that it was their fault the dotty and perc were probably infected on their
way to my house. <Which is why we recommend 4 weeks of quarantine for all new
acquisitions.> I don't have a second tank, would a FW dip help this kind of
fungal thing. <No. FW dips are for ectoparasites, not fungi or bacteria. Hard to
say if this was fungal as there is usually cottony matter associated with this.
Fin rot can be bacterial or toxic in origin.> Is the tank ok for fish again?
<Personally, I would wait 6 weeks to add anything. You should also learn the QT
lesson. A cheap 10G tank or an even cheaper Rubbermaid container with a heater
and a sponge or HOT power filter will do. Then 4 of the 6 weeks can include the
QT of your first new fish. Is the residual Melafix a problem for the
inhabitants? <I would recommend several water changes over the fishless period
to assure excellent water quality.> Thanks much, Lorin of Colorado <Hope this
helps.>

Disease Treatment Dilemma!
OK-- I am in week 3 now of a quarantine period,
following an Ich outbreak in my main tank. It seems I
have successfully treated the Ich with copper (10
days), & have since stopped & removed it from the QT
(10G). But here's my next dilemma--
<Always another one, huh?>
Originally I had the QT partitioned due to some
bullisome behavior from my Checkered Goby, with the
Goby on one side, & 2 Green Chromis + 1 Ocellaris on
the other side. I started noticing, however, that the
Ocellaris was pecking at the Chromis (he even pecks at
me when I'm siphoning out food/waste). The Chromis are
now missing numerous scales each. I have relocated the
Ocellaris to be roomies with the Goby. After the first
night, there was a noticeable nip taken out of the
Ocellaris' tail, but there seem to be no new wounds
since then. I think with his little fishitude they
have struck a truce.
<Let's hope!>
But the Chromis are what are concerning me. Its only
been a couple days since I moved out the Ocellaris,
but the missing scale areas on the Chromis are looking
a bit funky. I'm concerned about their developing a
fungal or bacterial infection.
<A valid concern...>
I've been doing 50% water changes daily to combat
ammonia & nitrites. I finally have ammonia on the
retreat since stopping the copper (ammonia was as high
as .5 to 1.0 during treatment, but now .1, if that),
but the nitrites are sticking it out (.1 to .25).
Yesterday I implemented a home-made above-tank
bioballs filter--a 2G paint bucket, with an Eheim
110GPH pump to send water up to a trickle 'plate'
(really just the bottom portion of another bucket with
numerous 1/8" holes drilled into it, & then a return
hose sealed into the bottom of the bucket. It flows
nicely. I dosed with Nitromax directly into the bucket
to try to kick start the colony (I have also been
double-dosing with Nitromax daily after every water
change). Hopefully this is animalistically out of
proportion to the QT & will become super-efficient at
removing toxins. Thoughts?
<It certainly is a bit of "hyperfiltration", but if it keep the ammonia level
down, then it is certainly a viable option. The last thing that you need here is
additional stress for these animals!>
So I guess what I'm getting to, is what's the best way
to treat the Chromis, now that I have stopped copper?
<Personally, I'd rely on very high quality water conditions as opposed to
another round of potentially stress-inducing meds...>
The Ocellaris & Goby look great. I am reluctant to
start re-adding copper or anything until the water
quality normalizes.
<Agreed...It may not even be necessary to continue to expose the fishes to
copper>
I am thinking now that after the 4th week of fallow period in the main tank it
will be safe enough to re-add the fish, but I don't want the Chromis to bring
anything into it, if avoidable. My
original plan was for an 8 week fallow period, but I'm
wondering if its getting a bit stressful for these
fellows being kept in such cramped quarters.
<I prefer a 6 week fallow period, if at all possible. A month is good- 6 weeks
is better...8 weeks is awesome! It may be a case of weighing the possibilities
of re-introducing disease to the display, or possibly losing the fishes in the
"hospital tank" do to environmental stresses. If you cannot set up another
alternate container (i.e.; a Rubbermaid, etc.), then you may want to re-patriate
the other fishes gradually and "roll the dice"! A tough call either way>
What I am considering is after the 4th week, I would
maybe move the Ocellaris & Goby to the main tank, &
then allow the Chromis some additional time to recover
from their wounds.
<Man- we're on the same wavelength here!>
Do you think it would be necessary to add some kind of antibiotic into the QT
for this?
<If you are dealing with a specific condition that warrants its use- yes. If
you're just trying to prevent a problem, then observation, careful husbandry,
and excellent water conditions may do the trick>
Would copper be effective against a fungal infection?
<Not my medication of choice...>
Or is there something better for this?
<Possibly more appropriate medication would be a product like Maracyn...>
How is my bioballs bucket likely to fare once its established &
then I add something to treat the fish?
<Antibiotics could be problematic...>
As always, thanks in advance for any advice you can
offer! Bioballs to the wall,
Pete Cushnie
<Hang in there, Pete- I think that you're on the right track...Good luck!
Regards, Scott F>
Chalk Bass problems
Hi there, my name is Rachael and I was hoping you could help me with
something. I have a 50 gallon marine tank, it's 6 months old and has set up
nicely. The water quality is good and we just recently purchased VHOs so we
could have some neat corals and an anemone. My question for you though has to
do with my Chalk Bass. << Keep him, great fish to have. >> He was the first
fish that we purchased, we've had him for about 5 months. Within the first
three or four days that he was in our tank, one of his eyes puffed out and was
like that for about a week. It went back to normal and within two days it was
all puffed out again, it looked as though there were air bubbles under his
scales, it was really big! But after about a week and a half, it went back to
normal. Then about a week later, it puffed out again, bigger than either of the
two times before, and it looked as though it were going to pop; well it didn't
then but it took about three weeks for it to go back to normal. While my
husband and I were going through this ordeal with our fish, we couldn't find any
sort of disease that matched the symptoms of our fish, so we sort of wrote it
off as an injury. We have about 20 pounds of live rock in our tank and he likes
to swim really fast in and out of the rocks, so it seemed plausible. About a
week ago, his eye was all puffed out again, worse than ever, and two days ago,
the top of it popped, so it was still kind of puffy at the bottom. The top
'skin' was hanging over his eye impairing his vision, and then yesterday, the
rest of it popped. I can't tell if he still has his eye or not because the
floppy skin surrounding it is blocking my view of it. I was wondering if you
knew if his eye might grow back or if he will possible be blind in one eye? <<
He is most likely blind in that eye. It is unfortunate, I would have taken him
out of the tank, and into a hospital tank the first time it happened. In fact,
I would still do it now, and treat him with some antibiotics from a LFS. >> Do
you know of anything that could have caused the puffiness, besides injury? Is
there anything I can do - take him to a fish doctor or something?
Thanks for your time, I look forward to your reply. << That is tough, good luck
with him. >>

Should We Freshwater Dip our Sick Fish, or Medicate the Tank?
Hi There, I'm new to your website and am getting much valuable
info. We relocated and set up our 90 gallon saltwater
tank. The tank has been conditioned and we had a large Chromis
in the tank for three weeks who has done great. The chemistry is all
good and the salinity is at 1.025 We added a 4" Blond Naso; a
3" yellow stripe maroon clown; a 4" Volitans lion and a 4" dogface
puffer. We purchased all the fish within 3 days of each
other from 2 different LFS's. << That is a lot of bio load to be adding to
a system. I would add one fish every other week, or something like
that. >> All were eating and looking good at the store. The
dogface puffer has come down with ICH. One LFS said to add copper to
the tank, which we now know is a big NO so we are not taking their advice.
<< I wouldn't do that either. I would rather catch the fish,
and move him to a hospital tank. >> The other LFS said he wouldn't do
anything and definitely do not treat the tank. They said generally
the dogface puffer is very resilient and that all fish have bacteria, etc. but
when they are stressed. they can develop ICH. << This is more along my
philosophy as well. I think fish are always vulnerable to disease,
but if healthy they just fight it off. >> Our puffer (Scooby Doo) has
stopped eating and is staying huddled in the corner most of the time, although
he does come out and swim around a bit. Also, sometimes when he starts swimming,
his side fin is stuck in his gill, but after swimming around for a while, it
comes out. << Not a good sign at all. I would remove him from
the tank, and treat him in a hospital tank. >> He seemed to be looking for
food earlier, but when I fed him the krill, he wouldn't go after
it. The other fish seem to be fine, although I am concerned that
there might be a spot on the Naso. We are getting ready to do a FW
dip for the puffer. We've made sure the PH is the same as the tank
and we are getting the water the same temp. << I don't think you'll get
the pH the same, but that is okay. After dipping him, I would keep
him out of the main tank. >> Please let us know what we need to do to save
Scooby and the rest. Do we need to do dips on the others and should
we treat the tank? << Dips is good, but stay away from treating the tank.
>>
thanks, << Good Luck. >>

Dropsy, I think...
I have a bit of a conundrum. I emailed you a few days
ago with a quandary about ich + Cyano, & an isolation
tank that is inhospitable at the moment.
<Okay>
Well, the Chromis I was concerned about now is showing
signs of 'pinecone' scales, which along with his
bloatedness, sounds like dropsy. I would like to
isolate him, but my isolation tank's nitrites are off
the scale. I'm water changing it daily & dosing it with
NitroMax, but I'm afraid it will be too late before I
can use it.
<Me too>
How contagious is dropsy,
<Stop! Actually, dropsy or dropsical conditions are NOT necessarily
contagious... the "causes" are not simply resultant from infectious disease, but
a combination often of environmental factors. Many times only one fish will be
so affected in a group, even of the same species>
& what are the odds of
successfully treating it when it seems pretty
advanced?
<Depends on the cause. In the majority of cases (IME) dropsical conditions go
unnoticed, undiagnosed, conditions are such that the animal perishes... but
particularly with isolating affected fishes, spontaneous cures are often
realized>
I'm not the kind of guy to flush a fish that
isn't dead yet, but I don't want him to wipe out my
remaining fish (2 other Chromis, 1 Checkered goby, & 1
Ocellaris) if he dies & I can't remove him soon
enough.
Thoughts?
Pete Cushnie
<If you cannot move the fish to separate quarters, simply do your best to make
sure it is receiving some food, do add (this will be fine for all your other
fishes) a teaspoon of Epsom Salts (yes, the same as humans use) per gallon of
water (only once unless you change some water out), and this will help reduce
the swelling (which is the root cause... dependent in turn on a few possible
inputs) inside the fish. Bob Fenner>
Dropsy, I think...
Hi Bob,
<Peter>
Thanks for your reply, but I regret to let you know
this little fellow perished about a week ago.
<Is our mail server THAT slow?...>
I was
able to move him to a 5gal I had sitting idle
(equipped with heater & filter), & filled it with
water from the tank. He didn't make it the night. His
name was Moe. :-(
<Goodbye Moe>
I would, however, be interested in a little
clarification on the adding of Epsom salt. Is it safe
to add it directly to the tank?
<In most tanks, systems, yes... not a good idea to use prophylactically however>
Should it be
pre-dissolved into a partial water change perhaps?
<A good approach, yes>
I
am just wondering how similar it is to regular marine
salt in regards to causticity upon mixing.
<... MgSO4 is a small component (synthetic and real saltwater is a mix of
several salts... combinations of metals and non-metals)... once again, I do NOT
encourage folks to increase/add the amount of magnesium sulfate in their water
regularly>
Hoping I never have to address it again,
Pete
<Be chatting, Bob Fenner>
Toxic Environment- Or Poor Collection Practices?
Help,
<Scott F. at your service>
Four days ago, I special ordered a Lionfish and a Leaf Fish from a LFS. They
arrived in shipping bag, and I immediately brought them home. The Leaf was
belly up when I got him home, but the Lion was fine. I bypassed acclimation for
the leaf since he was barely breathing.
<Hmm...a tough call there...>
I aerated the system, and the leaf perked up. The lion would not eat,
however. (The leaf ate two ghost shrimp soon after perking up.)
<That's always a good sign>
Both fish have had labored breathing, and the Lion finally had trouble
swimming. (Fine day one, Bobbed in corner for 2nd day.) The lion seemed to
come through, and started exploring the tank on day three. 2 hours later, he
was dead, with bloated gills.
The leaf currently stays under a rock, has no interest in food, and
seems to barely breathe. The water tests fine, the aeration has been increased,
and the temperature has been 76 deg.
<Well, sounds to me like you may be looking at a toxin of some sort. Are you
sure that the tank has no detectible ammonia or nitrite? No pesticides or other
household chemicals found their way into the tank? Do recheck.>
Could all this be a sign of Cyanide? I've just learned about cyanide catching,
and don't know anything about diagnosing. What are the symptoms?
<I doubt that this is cyanide poisoning. Typically, fishes that have been
collected with cyanide are unusually colorful, appear "dazed"; not responding
quickly to stimuli. They generally refuse food, but if and when they do eat,
affected fishes will generally die shortly after eating. I have not heard of
either of these types of fishes being collected with cyanide recently, although
I suppose it's possible. I'll bet that it may be environmental or a disease of
some sort. I'd continue looking at an environmental cause here. The truth is out
there; keep searching. Regards, Scott F>

Preventing The Spread of Disease
Hello,
<Hi there! Scott F. here today!>
I must tell you what a wonderful informing site you have. Most of all, your
willingness to share you knowledge with the world.
<Well, sharing our experiences and love for this hobby is really what the site
is all about! We're all in this together-learning and growing!>
I am in the aquarium maintenance business since 1988. Assume that one of my
clients' tanks had the ich parasite in their tank. As I perform my maintenance
on their tank, I siphon the crushed coral on the bottom of the tank. When done
with this, I wrap up my Python siphon hose, finish my job, on to my next client.
The first step is to fill up the garbage can with tap water for make up water
for the salt water I'm going to remove to do maintenance on this tank. If there
were any parasites in the hose going from the first client to the next do you
feel they could be introduced into the next clients tank?
<Great question. Quite frankly, I'd have to say that the possibility exists. It
may be remote- but it is definitely a consideration>
They would be flushed into the garbage can upon the filling but would these
critters be able to withstand the fresh chlorinated water and stay alive long
enough to be introduced in the second clients tank? Just thoughts I have.
<Again- it is a potential problem; one that needs to be considered. You could
definitely rinse all equipment with hot water after each use, and that can help>
I do all I can to keep tanks separate- like every client has their own scrub pad
under there own tank. I never use one pad on all my clients tanks. Stopped that
practice years ago.
<Excellent practice on your part!>
I often wonder about that hose transferring the bugs. I even use a different
hand towel at every client's tank so not to pass the bugs from tank to tank. I
can't ever remember one tank getting inoculated in this manner.
<It is unusual, but not impossible by any stretch! It may be a good idea
(although probably not as well received by your clients, who would have to foot
the bill!) to provide each tank set up that you install with a set of dedicated
maintenance equipment (i.e.; siphon hose, nets, scrapers, scrub pads, etc.)-just
factor these items in to the cost of each setup that you install. This would be
the ultimate way to eliminate this possibility.>
Anytime I've had a tank come down with parasites is when I bring in new fish.
<Probably the most common way that disease is introduced to new aquariums.
Consistent use of a quarantine procedure is, without question, the best way to
prevent disease from getting into your system!>
I always copper up the tank for at least a month upon adding new livestock.
<Ya know what? Simple quarantine might be a better way to go! Certainly easier
than running copper preventatively, IMO>
Well it's just a thought I've always had, and since you seem to have all the
answers to so many problems with marine fish and the business I thought I'd ask.
<Well- we don't have ALL the answers- but as lifetime hobbyists and aquarium
industry pros (as is the case with a number of our WWM contributors), we can
provide a pretty good depth of information for our readers!>
Once again you sure do a wonderful service to us all , whether in the business
or just hobbyist. All one needs to do is read and learn.
<Amen- Jim! >
Thanks so much for you time and answer, Jim Jesko Aquatic Designs.
<Thanks for your sharing, Jim! Continued success to you and your customers! Keep
sharing! Regards, Scott F>
Fish Doc in LA?
Hmmm... I'm not familiar with a fish doctor/vet in LA
but have cc'ed this to Bob for posting on the daily
FAQs (will holler back to you if we get a reply)>
The Magnesium sulfate was a good move in my opinion.
Id the fish in a bare bottomed QT at this point? Not
critical, but helpful for treatment (may be required
pending meds).
Be generous with the Epsom salts... I dose a heaping
Tablespoon per five gallons the first time, and then
follow with a half dose 3 days later. If the ailment
is simply blockage or a little bit of fluid buildup,
this often works.
Please do let me know how this works out overall. Best
of luck, Anthony
<<Don't know of a fish doctor in L.A. per se... would call a few of the
larger stores, service companies in the area for a lead here. Bob Fenner>>
String Feces (5/23/04)
Hello crew! <Steve Allen today>
Thanks for all the wonderful information. <A pleasure to play a small part.> You are truly a public service that has saved a lot of lives, mostly aquatic...but possibly human if those who share you life (read: finances) are
not, shall we say involved (read addicted) to the hobby as you are! <Understood. I convinced my wife that SW aquaria are a safer and cheaper male mid-life crisis expenditure that several others we've seen in our neighborhood.>
Anyway here's my situation. I had serial ich and Amyloodinium outbreaks back in March. <Ouch> I treated the ich via hyposalinity, only to have the
Amyloodinium follow, which I treated with copper. I let my original 15 gallon reef tank go fallow for well over 6 weeks. The fish were in the 10 gallon QT tank for over 6+ weeks as well. 2 weeks ago I set up our new 46 gallon. I moved the 45lbs
of live rock from the 15 to the 46. Last weekend I moved the fish (fairy wrasse,
YTB damsel, Firefish goby and a royal Gramma) into the 46. <Monitor your water parameters. Even with the old LR, the tank's biofilter might not have been ready for all the fish at once after only a couple of weeks.>
I released the wrasse, damsel and goby at night and kept the Gramma in a floating breeder which he has lived in while in QT until the next morning. I wanted to allow everyone else to get established first because I had a problem with aggression
with the Gramma. <Can be a problem sometimes.> Since being released he has been hiding, not eating and is producing white stringy feces. <Uh-oh> So I checked WWM. I found white stringy feces
associated with both parasitic and bacterial infection. I am unsure how to proceed. How do I tell which it is? <Not really possible, though bacterial infection can have other manifestations as well, including bleeding into the skin.> Is this contagious? <Bacterial infection isn't always passed on. Healthy fish with good immunity can fight it off. Internal parasites lay eggs and can be passed on.> So far everyone else seems OK. Do I need to remove all the fish and treat everyone? <Since you have a QT, I'd suggest you just pull the Gramma.> Could this be a stress reaction? <More than just that.> Might this resolve on its own? <I doubt it.>
If not, do I use antibiotics or an antiparasitic? <Probably both.> If treatment is require, what do you recommend? <Search WM for internal parasite
treatments. One option would be food laced with Metronidazole (AKA Flagyl), which may treat both, depending on which bacteria or parasite you are dealing with. This is often available at LFS or can be obtained online.>
And just to complicate things, after removing all the fish from QT, we acquired a tiny purple tang who is now in the QT tank. Do I put everyone together, exposing everyone else to a potential new ich or
Amyloodinium carried by the tang? <NO. To be quite frank, you should return the Tang unless you are
planning on upgrading to a 100G tank within a year. This is an aggressive fish that will grow to as long as 9" and should not be kept in
anything smaller that 100G. Some would say 75, but given its personality, that's too tight IMO. Once you get everything settled sown, you can choose a more appropriate fish for your size of tank.> Help!
Also the 15 had an eclipse hood, which I moved to the QT tank. Is it possible to put this back on the 15 with inverts, if the
BioWheel and filter are replaced or does the copper get into the plastic as well? <That is a potential concern, but I doubt it. A good, thorough cleaning should suffice. Plastic is far less likely to absorb copper than minerals like rock and sand are.>
Thanks for all the help this site provides. I don't know what I would do without it. I normally find answers to my questions there, but I was not sure what to do in this situation.
Sincerely, Michelle <Hope this helps.>
Swim Bladder Problem? Or Something Else? (5/14/04)
Hello, <Hi! Steve Allen here.>
I've had a couple of saltwater tanks for about 19 months now, and in so short a time have seen many strange things happen. <Not surprising.> I've researched various issues on your site and have found in invaluable in resolving many of those issues, but I have encountered one that has me a little stumped. <Don't you hate that?>
Sparing you all the details (unless you require them), the tank has been running for 19 months, all of the other fish, corals and inverts are fine, all levels are optimal, with the exception of nitrate, which runs at about 10 ppm <not too bad>, salinity is 1.024, temp is 77.
About 4 months ago, I acquired a juvenile blonde Naso. She spent the first month in quarantine and although she was thin, appeared to be otherwise healthy. In quarantine, she put on weight and continued to gain weight when she moved into the main tank. About a month following that she began constantly eating air bubbles under one of the filters and would spend the majority of the day doing so. <Odd> By the end of each day, her stomach would be terribly bloated and she would seem to be struggling a bit to swim. By
morning, her stomach would be back to normal and she would at least start her day swimming normally, but begin to eat the air bubbles all over again. Over the last week or so, after lights out she seemed to be having a more difficult time and would kind of position herself with her nose pointing down toward the substrate and would struggle for many hours after lights out.
Yesterday morning, I found her lying on the substrate, kind of propped up against the glass. She would swim a very short distance, then sink like a rock to the bottom, sometimes lying flat on her side, other times, propping herself up in the rock-work. My best guess is that something has happened to her swim bladder. <Hard to say. This behavior is also a symptom of impending death.> I moved her back to quarantine and she was still alive this morning. She is eating and doesn't have any marks on her, but is almost constantly displaying her fright/sleep coloration.
So I guess my questions are: does it sound like the swim bladder may have ruptured? <It really sounds more serious to me. The listlessness suggests this.> If so, is there any possibility of recovery? <This is hard to treat. Read more by searching the term on WWM.> Is there anything I can do to help her or (I hate to even think of it) is my best option just to put the poor thing out of her misery? <There is usually hope for a fish that still eats. Start with pristine water conditions and no air bubbles in the QT. Consider treating with antibiotics as well.>
Any input you could provide would be most sincerely appreciated.
Donna <I hope this helps some. I'm a bit stumped here too, especially by the bubble eating.>
Mystery Bump
Hello Wise ones!!!
<Yikes- "wise"- Who needs that kind of pressure? Scott F. here today!>
I did not find what I was looking for in the web site, so I need you HELP!!!! Two days ago I found a medium-sized bump on my Banggai Cardinal. He's been eating well so far, and he swims and hangs out in the middle of the
tank, like when I first got him a year ago. What do you think this bump is???
Thanks for all you do!!!
<Hard to say...Could be anything from an old injury to a possible parasite. If you can supply a picture, we could possibly make a better
guess. If the fish is otherwise healthy, eating, and active, I'd just keep an eye on him and only take action if the situation dictates. Keep those fingers crossed! Regards, Scott F.>
After The Disaster (Re-Populating A Tank After A Wipeout)
Hello, After having some butterflies for 3 mths in a 4ft tank, a new one
spread White Spot to the rest. Although I have tried some Marine Cure
products, the fishes slowly died.
<Not familiar with these products, but I would advise against using any
medication in the display tank...>
I would like to know if I need to restart all over again by putting
new water 100% and go thru the nitrogen cycle again or what? Please
advise. Thanks. Ramlan
<Well, Ramlan, if you lost all of your fishes because of this illness, I'd
let the tank run fallow, without fishes, for at least a month or so. Yes, large
water changes would be a good idea, too. If you continue to add small amounts of
food to the tank while it is empty, you'll be providing the bacteria with a food
source, and can hopefully avoid the need to re-cycle the system. However, do
test for ammonia and nitrite as you go, just to be sure. Regards, Scott F>
URGENT! Sick Purple Tang NEED HELP ASAP! 5/4/04
Hi, <Hi Lawrence, Leslie here this morning.>
I came home from work today and my tang was darting around the tank erratically
and would swim around occasionally tilted like he was trying to scratch but not
quite.
<Sorry to hear that>
He also seemed to be breathing a little rapid.
<No doubt with all that frantic activity>
I observed him for 2 hours and no improvement. I have had him for 2
years and 10 days ago moved him into the new 120gal FOWLR tank. SG
is1.024, temp 77 nitrites ammonia are 0 and the nitrates are 1ppm or less. PH
is 8.2. The fish is still eating.
<Water sounds good and eating is an excellent sign>
My puffer had 3 white spots on his fins for 10 days and is healthy appearing, I
have also had him for 2 years. Any way, I tried a fresh water dip
with RO water pH and temp adjusted and the tang just
laid on his side and looked distressed so I stopped it after 1min.
< The right thing to do>
( i know that it will not help for that short of a time) so put him in my
hospital tank with copper sulfate. I am assuming it is ich.
<Hard to say without the tell tale white salt granule like spots
but maybe a possibility. Something was certainly bothering him>
Did I do the right thing.
<Well to be honest I am not sure I would have medicated so quickly without
more obvious symptoms. I am an advocate of water changes to start when the fish
appear stressed, regardless of testing that indicates parameters that are within
normal limits. There are some other possibilities for the erratic
behavior you described. The first one that comes to mind is stray electrical
current. If you do not have a ground probe on your tank I would highly recommend
one as well as a GFI ....Ground Fault Interrupter device for any
electrical outlet near water. You may find these 2 articles on Electricity,
Marine Aquariums and GFIs helpful.
http://www.wetwebmedia.com/elecmar.htm
http://www.wetwebmedia.com/gfcimarines.htm
Since you Puffer also was showing signs of disease 10 days ago it certainly
sounds like something is going on. You might want to have a look at this article

>
I don't want to lose the little guy. <Of course you don't>
Our fish are part of our family. <Of course they are as they should be>
<If the fish seemed better in the hospital tank prior
to adding the Copper then it may be just getting him into a different tank
removed the stimulus for the erratic behavior. If not and the copper seems to be
helping I would complete the treatment you started and keep the fish in the
Hospital tank for at least 3 to 4 weeks post treatment.>
Thanks! I hope you can reply ASAP
<Your welcome! I hope you fish has settled down and is doing better.

Nasty Disease?
Hi Crew,
<Hey there! Scott F. here today!>
I am having major problems as I am losing fish left, right and centre, in the
past 3 weeks I have lost the following from 3 different tanks:
5 ft tank
1 Russell's Lionfish
1 Blue Cheek Goby (part of breeding pair)
1 Picasso Trigger
quarantine tank:
1 Cleaner Wrasse
<Ohh...one of my pet peeves here- a really bad choice...>
1 Cowfish
4 ft reef tank:
1 Flame Angel
It seems to be very sudden that these fish die, within a couple of hours, as my
Flame was feeding 3 hours ago and seemed fine, and when I went downstairs, is laying
in the bottom of the tank almost dead. Gave quick freshwater bath, and put
in with Cuprazin but died very rapidly.
<Not sure what the medicine that you mention is, but I ask you- why use a
medication if you are unsure what the "disease" is? If you are
operating on the assumption that it is a parasitic illness, then you are on the
right track, i suppose.>
The only things I could see was on the blue cheek goby, it had a type of red
bloodish color on the usually yellow nose, all seem to have the skin missing
between the spines on the pectoral and dorsal fins? As I said, this is a very
rapid and sudden demise
the nitrites are at 0 the nitrates are a little high at between 25 - 50 ppm ph
8.2 ammonia 0
<Hmm.. to me, it sounds like it might be some type of poisoning. My initial
thought would have been "ammonia toxicity", but your water conditions
seem to be okay. It could be an extremely virulent parasitic condition, such as
Amyloodinium (Marine "Velvet") or Brooklynella, which can kill with
remarkable rapidity>
I have been using Amquel to reduce the nitrates on advice from my LFS.
<This product can help "prep" source water, but you want to look to
more established techniques to reduce nitrates. See the WWM site for more on
these techniques>
Each tank has an external filter. The reef has an air driven protein skimmer and
undergravel filter as well as external filter.
I have completely stripped and refilled the 5 ft fish only with live rock
and live sand tank which now contains:
1 Dogface Puffer
1 Orbiculate Batfish
1 Panther Grouper
1 Tassled Filefish
This has an external filter and venturi skimmer,
the 4 reef has live rock and live sand, external filter, undergravel filter,
air driven skimmer
live rock and sand
I keep losing anemones in this tank such as Bubble Anemones, but
everything else seemed fine until tonight, in this tank there is:
2 Common Clowns
1 Torpedo Goby
1 Scooter Blenny
1 Yellow Tang
1 Foxface
1 Blue cheek Goby
1 Cleaner Wrasse
Please help as I don't want to lose anymore. Thanks in advance, Crew. J Millar
<Well, I'd operate under the assumption that a nasty parasitic infection is in
play here. I'd consider letting the tanks in which the losses are occurring run
fallow, without fish, for a few weeks. If this is a parasitic illness, then you
need to let the parasite population "crash" for lack of hosts.
Continue observing the tank carefully, adjusting environmental parameters if
needed, and treating the affected fishes as required...Hang in there! Regards,
Scott F.>
Learning The Hard Way...
Heya !
<Hi there! Scott F. at your service!>
Sorry for the long question but I'm kind of in a bad way and seek your advice! I
posted a few threads on WWM in the last 2 weeks and would like your spin on it.
My tank is 3 months old and fully cycled , but man, it's the tank of DEATH!.
<Sounds like a new movie...>
Every fish I put in it dies. I started w/ a pair of tank raised
percula clowns and they were great, eating swimming etc... ( No QT tank as of
yet ).
<Trust me- get a quarantine tank...A huge benefit to your fish-and your
sanity!>
After 2 weeks, I added a yellow tang that died in just 2 days.
Weird, but I guess I just bought a fish that was sick anyways, although he
looked healthy to me, he ate and swam fine in the tank.( still no QT yet)
<There is a pattern here, huh?>
The 2 clowns were still bright colored eating and looking good. I waited another
week and bought another yellow tang and put him in the display tank. (still no
QT as of yet).
<Dude, you're killing me here! Do you realize that with the money you spent
on these fishes, you could have bought a basic 10 gallon tank, sponge filter,
and heater? C'mon...first things first!>
Then after a week 1 clown started to lose his color and also had rapid
breathing, I tried to catch him but all attempts were
futile. He had enough strength to avoid capture. He evaded capture for another
few days till we found him dead in the tank.
<These symptoms sound like you could be dealing with either a virulent
parasitic disease (like Amyloodinium), or possible metabolite or other
poisoning. Fishes don't usually die this quickly unless something is seriously
wrong. I'd read up on the WWM site regarding fish selection. You might be
picking some low quality specimens. Do consider other stores, too. Also, do test
your basic water parameters (ammonia, nitrite, pH, specific gravity, and
temperature, to make sure that all are in line).>
Well this prompted me to get a QT , its only 5 gals but its all that would fit
my budget atm.
<Thank you! 5 gallons is better than nothing! I raise my Thai Iced Tea in a
toast to your future success as a result of embracing the quarantine process!
Don't get me wrong, however- a quarantine tank will not "cure" sick or
low-quality fishes. It will, however, give you a chance to observe,
"harden", and treat fishes which may be suffering from the rigors of
collection and shipping>
A few days passed and the other clown started to decline in the same manner as
mentioned above and this one to died after a few days. The QT was up and running
so I dismantled my LR and caught the Yellow tang, who at this point
had little white specs all over him and had a cloudy eye. I brought the sal down
to 1.018 and took the temp to 80 in the QT. I bought CopperSafe to treat ICH and
administered it to the QT and the levels were at .25 ppm for 4 days, I was doing
1 gallon water changes daily to get the copper to 0. Well, during the 3rd day in
qt the Yellow Tangs eye burst, he was still eating whatever he could see and the
white spots on him turned to brown spots. From the copper?
<Possibly. Although copper is a very effective medication for parasitic
diseases, some fishes, such as tangs and Centropyge angels, don't always take
well to it. Formalin-based products are a good alternative, IMO>
I continued water changes and monitored him, well unfortunately when I got home
last night the lil guy was dead in the QT. It seems that my efforts to try and
save the fish probably killed him by treating w/CopperSafe ( I found
out in the 911 forum that copper is detrimental to tangs ). The levels in my
display tank are as follows:
Temp -77
PH- 8.2
sal - 1.023
ammonia - 0
Nitrites - 0
Nitrates -5
cal - 450
copper - 0 ( I ran a test on it to make sure )
<Well, your water conditions sound fine. I'd narrow down the problem to poor
quality fish; ones that may have been sick, or exposed to illness at the LFS>
Here's my question : I know to let the Display remain fallow for 6 weeks to rid
it of any Ich parasites. But now that I've used copper in my QT will it leach
into the plastic filter etc?
<I wouldn't be overly concerned about that. Also, you should break down and
sterilize the QT when you're done using it. It's not a permanent feature>
I'd hate to buy another fish, put it in quarantine for a month , dip him out and
place in my display and inadvertently put copper into my display.
<Don't stress over it. You'd only be talking about a few drops of water with
copper in it. Not enough to cause problems, IMO>
I also used the qt to mix/aerate my water for bi-weekly water changes.
<Wooooaaahh! Bad, bad idea! The quarantine tank is just that- a quarantine
tank...It's not a water reservoir, storage container, breeding trap, etc. Buy
some inexpensive Rubbermaid containers for that, okay?>
Is there any way to rid the copper from the filter
assembly, etc?
<Run some Poly Filter in the water. That should get rid of most of it. Any
copper which has leached into the plastic would be of virtually no consequence,
IMO>
Will it be safe to use to mix water with etc prior to water
changes?
<As above- get some dedicated containers for this>
Any suggestions as to why my tank is the death card for fish? Did the original 2
clowns infect the tank and I'm feeling the ramifications of no qt from the
beginning?
<Excellent theory. I think that is exactly what may be happening>
BTW , all inverts in my display are doing fine. The
snails , crabs, and coral frags are doing well in there. Sorry again for the
length , I'm just a little disappointed ATM and am at a loss as to why this is
happening.
Andy
<It's okay, Andy- you are learning- and learning fast! Think about what
you've learned from this nightmare already: 1)Use extreme care in selecting
quality fishes 2)Quarantine all new arrivals 3)Copper is not acceptable for all
fishes...Impressive, huh? Just take it slow, keep learning from your mistakes
(that's how we all learned, BTW), and share with others. You're on your way to
success! Good luck! Regards, Scott F.>
Injured Chromis?
Good morning. Yesterday afternoon I bought 3 blue-green Chromis,
which are
to be the first additions to our 75 gallon tank. After a 6 minute dip
in
buffered fresh water and Methylene blue, I transferred them to a 10 gallon
quarantine tank. All tolerated the dip well, and by evening were
swimming
together around their new temporary home. Although all looked healthy
last
night, this morning one of them has a bruise-like vertical line through his
mid-section. Only on one side. He's swimming normally,
breathing normally,
doesn't appear stressed. Having no fish experience, my best guess is
a
bruise - maybe a net injury or something?
<Likely so... may develop into a secondary (bacterial) infection>
If it is a bruise, will it heal
on its own with good water quality. and how long before I should see
improvement?
<Should and a week or two>
Please let me know if there are other possibilities I should
be aware of, or what I should be watching for/expecting. Thanks. Suzanne
<Be chatting, Bob Fenner>
Another Convert To Quarantine!
We just lost a Blue Tang to ich, and now this morning we found our Singapore
Queen dead this morning. She was fine yesterday and was an extremely healthy
eater. We want to get new ones but are not really sure of the proper quarantine
process. Obviously we need another tank, but do we put water in it from our
existing tank in it, do we need a second heater, skimmer etc. How long do we
need to quarantine them for. Current tank
77 gallons
consists of
40% full of base and live rock
2 clowns
20 crab
4 clams
2 shrimp.
We are so new to this and hope it is because we jumped into getting fish to
quickly. The tank is only 6 weeks old. I have since done more research and it
seems it may be due to new tank syndrome. We have lost 2 cleaner wrasse as well.
I really do not want the fish to suffer and want to make sure
that it is done correctly this time. Not to mention spend the money and then
have to replace them.
Kelly Aiello
<Well, Kelly- quarantine is possibly the single most effective thing you can
do to assure long-term success in the hobby! Here's a link to an article I wrote
that may give you a helpful introduction to the process:

Beginners mistakes 2/12/04
I've got a bunch of bad advice and need to be set straight. I
bought a Indian Regal and a Queen angel...both @ 5-6 inches.
<the Queen I like (hardy and well suited to captive life if you have a huge
aquarium (over 200 gallons)... but the Regal Angel is one of those fishes that
most always should be left in the ocean. Very unlikely it will fare well even
without that mean queen in the tank>
I didn't QT them as I have now read to do. I added them 6 days ago. They
were fine and both started to eat, pick at the rocks, etc up until yesterday. Then
they started to fight. I grabbed both fish and took them back to the
LFS. They would only take back one of the fish. I'm stuck
with the Regal.
<not a surprise... the LFS should not have even sold you the Regal without
advising you of how (extremely) difficult they are to even keep alive>
I'm assuming this is from the fighting, but the Regal has a white patch about
2-3mm behind one of his fins. The fin now has some of the white stuff
on it as well. I told him about this site and that I wanted to
purchase a QT. I bought a 10 gal tank and set it up with water from
my main tank. They sold me copper power and told me to follow the
directions. I have the Regal in the QT with copper in it.
<holy cow?!?!?! This LFS is in the biz of helping you kill fish. It is long
been known (30+ years) how sensitive Angelfishes are to copper. My advice is to
do a large water change and add a PolyFilter or some other adsorptive chemical
media and get that copper out ASAP>
Everything I read it seems that a FW dip would be better. Should I
take him out of the copper QT and dip him?
<yes>
What should I dip him in....the LFS store says I'm pretty much an idiot and the
Regal will be fine in about 3 days in the copper.
<they are not admirable sources of information on aquatic husbandry.
Frankly... I hope they are simply ignorant and incompetent, instead of
nefarious>
Further, I now have noticed my Sweetlips (6 in) scratching his face on the
ground.
<oh, my friend... a Sweetlips makes the Regal look easy to keep alive. These
are serious beginners mistakes. The odds of the angel or the Sweetlips being
alive in 2 months let alone 6 is very small. Please research the species you
like before (!) you buy them. The burden really is on you and me to be educated
consumers, and not rely on advice wholly from people trying to sell us stuff.
Sweetlips need enormous tanks (see fishbase.org for their staggering adult
size)... and they need a constant supply of gut-loaded live foods to survive.
You need a breeding tank of guppies or grass shrimp (better) here>
I can't see anything on him but I'm worried some type of fungus is running
through the tank. Can I treat the whole tank with something? I
only have FOWLR. I have over 300 lbs of rock and can't catch all the
fish without taking all the rock out! YIKES!
<not that bad... get some garbage cans and use a pump to drain the tank...
catch the fish in an inch of water... and then refill the tank quickly (15-20
tops)>
Should I just leave the main tank and see what happens?
<they will die>
What should I have the temp at (it's 77 right now and I can raise or lower it to
anything). SG is 1.020...
HELP>>>>SO MANY QUESTIONS!
<please consider getting and reading two very good books before you buy
another fish: "The Conscientious Marine Aquarist" by Fenner... and
"The New Marine Aquarium? by Paletta. You are also encouraged to spend some
time reading the wealth of free information we have here on our wetwebmedia.com
website. Had you done so first, you would have never bought that angel or
Sweetlips. Wishing you the best of luck, Anthony>
Beginners mistakes II 2/12/04
You are so right. I just got and read the entire book....by
Fenner. What an idiot I am! Now I'm trying to remember everything I
read, but it is tough and not every question can ever be covered in one book.
<yes... correct my friend (about the remembering everything you read part...
not the idiot part <G>). Just remember to revisit your best references and
the Internet, local aquarium clubs, etc. before you buy a new fish. Do resist
all impulse purchases and any others before you have a thorough knowledge of
what it needs to keep it and if you can meet those needs>
Well my Regal Angel is going to die almost for certain. He won't eat
at all.
<I'm truly an optimist... but the statistics don't lie, and your regal is not
bucking the trend symptomatically I'm sorry to say. Add to that the LFS selling
a less than ideal specimen/locale (Red Sea and Maldives orange throat regal
angels are much better suited for captive life)>
All the fish have ICH. I'm positive of that. I have taken
all fish out....yellow tang, Sweetlips, Sailfin tang, Maroon clown, lawnmower
blenny and two damsels out of my 250 gallon tank and put everyone in a 35 gallon
tank. (WAY TOO SMALL!)
<yes... but for the short stay and with daily water changes siphoned from the
bottom, you can cure Ich in 8 days (even without meds, the siphoning is so
effective if done daily to break the parasites life cycle). After 2 weeks of
disease free symptoms they can return to the display>
I have been doing a 5-7 gallon water change about every other day. As
well as treating the water with Prime to try and keep
the ammonia in check. The ammonia is reading 1ppm at the end of each
day.
<it would be much better to do daily water changes here and add a cheap
sponge filter. Some meds like Formalin plus FW dips when possible would help
too>
I tried to give fish back but they won't take them. They have lost my
business now.
<no worries... any store that would sell a Sweetlips and a regal angel to an
uninformed consumer (if anybody but a specialist) needs to learn a lesson or
find a new business as far as I'm concerned>
I read to leave the tank "fallow" for 6 weeks. Is this what
you
recommend?
<yes... 4-6 weeks usually does the trick>
Any way to speed this up? Can I turn the temp up?
<a little, but not too much for fear of hurting far more>
I have only live rock in there and 1 cleaner shrimp. I have been
feeding the QT every other day only one cube of Formula 2 and one cube of Mysis
shrimp. I want to avoid over feeding so I can keep the ammonia in check.
<yes... correct>
Everyone is eating like they are starving, except the Regal of course.
<try a freshwater clam from the pet store... put it in live (or notch the
back hinge to open it faster) and let it slowly open up (dying yes) in seawater.
Angels usually love this. If yours eats it, refill the clam shell with frozen
food. Condition the behavior. Pull the clam after a couple days if it is ignored
though>
I have only ever seen him pick on the live rock when he was in my main tank. Will
they eat anything?
<your mysids are a good try... some live brine if you must (soak it in
vitamins like Selcon) for a temporary fix (do not feed long term)>
I saw him eat pellets in the store but he had toss them up
in the bag on my way home. They have been in copper power for a week
now. Will the ich be dead?
<not likely.>
I have see only a spot here or there.... but I think
it is gone in the QT.
<even without seeing spots there is likely some. Unless you have been dosing
copper twice daily and testing to maintain therapeutic levels. Since the angel
is still alive (copper sensitive) I don't expect that you have been adding
enough copper to kill all Ich>
I have a POLY filter... should I use it now?
<I would... to get the copper out while the angel lives>
How do I treat for Ich w/o copper?
<Formalin (Aquarium Products makes a hobby dose) and FW dips>
I also FW dipped each fish in methyl blue for
6-8 minutes each on 2 separate days. Should I do this again?
<helpful yes... but again be careful with the angel. Organic dyes are like
metals to angles... very sensitive>
The Regal infection is cleared up and he is active but won't eat.
<heehee... he's poisoned by copper and Meth blue <G>. Give him some
time my friend. It may still work out>
The LFS tried to sell my Kick-Ich but I said no way after reading your website.
<what a crock! heehee... you may as well hang a clove of garlic from each
fishes neck to ward off vampires while you are at it :) >
Wow...I truly suck! Thank God I found your website before I destine
some more gorgeous fish for a sure death.
<one last recommendation... do seek (mail order with Formalin if you must)
some Sweetwater plankton. Its a brand of slurried FW plankton in a jar that is
VERY well received by finicky SW fishes. Do give it a try for your angel. Bets
of luck! Anthony>
HELP! (Ian's turn)
I've got a bunch of bad advice and need to be set straight. I
bought a Indian Regal and a Queen angel...both @ 5-6 inches. I didn't

or some type of protozoan?>
Everything I read it seems that a FW dip would be better. Should I
take him out of the copper QT and dip him? <well since he is already been
introduced to copper you as might as well leave him in their, after all copper
power is not as potent as the run of the mill copper medication> What should
I dip him in....the LFS store says I'm pretty much an idiot and the Regal will
be fine in about 3 days in the copper.<he should be>
Further, I now have noticed my Sweetlips (6 in) scratching his face on the
ground. <probably a parasite of some sort within his gills> I can't see
anything on him but I'm worried some type of fungus is running through the
tank.<most likely not fungus...do dump him in the QT aquarium a treat him
with copper power, Also make sure you keep those fish out of the aquarium
because your aquarium is infested with parasites that can live without a host up
to a month or more> Can I treat the whole tank with
something?<I wouldn't...copper compounds of any sort are/can be toxic to the
fish and plus you have liverock> I only have FOWLR. I
have over 300 lbs of rock and can't catch all the fish without taking all the
rock out! YIKES!<Wow...don't waste your money that you spent on
the live rock by killing all the organisms with copper...just keep your fish in
a QT aquarium for a couple of months...I would suggest purchasing a larger QT
aquarium though>
Should I just leave the main tank and see what happens?<definitely NOT> What
should I have the temp at (it's 77 right now and I can raise or lower it to
anything). SG is 1.020...<That should be ok>
HELP>>>>SO MANY QUESTIONS!<good luck, IanB>
HELP!
thanks. I pulled all fish out and put them in a 35 gal QT
tank. Problem is
the ammonia swings. I have been changing 7 gallons every day or so,
but I
still get ammonia reading 1-2ppm. The fish are all eating well (about
once
every 3 days) except the Regal angel won't eat anything.<those angelfish
rarely survive....he is probably becoming another
"statistic"> He used to pick on
my rocks only. The spot on him has cleared up and I'm planning on
leaving
the 250 gallon fallow for 6 weeks.<good thinking> Any
suggestions for what to give the
Regal to eat?<A bible, a four leaf clover, a ton of luck...jp Their staple
diet in the wild
consists mainly of coral polyps unless you have 30 dollars every 2-3 days to
spend
on some coral frags then I believe your angelfish will be a goner
:(> Can the QT be treated daily with Prime to take out the
ammonia?<I would not treat it with anything...just continue to dilute the
ammonia with water
changes, Good luck with the Regal Angel and everything else, IanB>
Thanks...
Treating Ich in QT 2/13/04
OK, I got it. The main tank has never been dosed with anything.
<great to hear...whew!>
Only the QT. But has sand in it so I'm taking that out now.
<yes, please do... it harbors parasites and it buffers medicants>
I will siphon from the bottom every day. The tank is 35 gallons but
the actual water I believe is only 26 when you minus the wasted space with the
filter built in the back. How many gallons would you pull out everyday?
<as little as it takes to maintain water quality (zero ammonia) and sweep the
bottom entirely with a siphon. As little as 5 gallons if the QT filters are
conditioned (old filter media used)>
Tonight I just noticed my regal has a small white patch on his right side front
fin. What is it?
<Yikes... no way for me to say without a pic or better description than
"white patch". Please do take the time to review the pics, articles
and FAQs on marine fish diseases we have posted in the wetwebmedia.com
archives>
It is also on his side directly behind where the white patch is on his fin....
not sure that makes sense. It is not very big
but noticeable.
<understood... but could be any of a long list of things>
If Ich does not float what is tiny and white and pin size and you can see it on
the glass of your tank and floating around the tank?
<microcrustaceans (copepods) and/or microbubbles. Other particles certainly
possible. But Ich has no significant free-swimming stage that it can be seen with the
naked eye. Ich will not live on or browse the aquarium glass either>
I saw it on the fish for 2 days then it disappeared and then came back a few
days later. I assumed it was Ich.
<Hmm... do be sure here. Stressed and sick fish often secrete mucus which
allows bubbles and sediment to stick to them. Focus on one particle and see if
it moves after some hours (ich does not move around)>
At any rate, I'm leaving the main tank fallow for 4 weeks with just 300lbs of
live sand and 300 lbs of live rock. As for the
QT I'll get rid of the sand. Should I put Formalin in there and for
how long?
<as per the mfg recommendations for the brand/dose you buy>
I'm ordering another poly filter, some plankton, Selcon and going to find a FW
clam. Anything else? Thanks again.
<some medicated flake or pelleted foods would be great to use and keep on
hand. Also, do read through the articles on Ich/Oodinium by our friend Steven
Pro here:

Unexplained Blindness in Fishes? 2/6/04
Hi
<howdy>
Sorry about the length of this email just thought I would give you the history.
<OK>
I have a problem which I can not find a resolution for in either
books, internet or local advice. The problem is I am experiencing my marine fish
going blind overnight for no apparent reason. I'll give you some background
first.
<Hmmm... let me say that blindness in fishes is not at all uncommon,
particularly with large predators and herbivorous fishes due to improper diet
over time. Such deficiencies are well defined and studied. Do consult fisheries
data instead of hobby literature>
System:
120G tank with crushed coral substrate
About 30Kg Live Rock
10G Sump with plenum
Skimmer
Return Pump
Powerhead in main display
Compact Fluoro lighting
Corallife salt
Temp stays at a little high but constant 28.5 degrees C
Ammonia: 0
Nitrites: 0
Nitrates: fluctuates between 5-10
Salinity: 1.023
Ph: 8.1
Calcium: about 420
KH: 130
Tank was established Sept 2003 waited for tank to cycle using the live rock for
about 8 weeks before adding any livestock
Current inhabitants:
1. Female bird wrasse (first fish introduced to tank and doing well)
2. 2x Blue/Green Chromis
3. Harlequin Tusk (the most recent introduction)
4. 2x Red Stars
5. 2x Hermits
6. 2 small urchins (came in on liverock)
7. 2 small crabs (also came in on liverock)
8. 1x Sarcophyton
9. 1x Lobophytum
10. 1x Sinularia
11. 20x assorted size Corallimorph
12. 1x small BTA ( I now know I should not have added this with the corals
but they seem to be getting on at the moment)
All inverts appear to be doing well. Iodine and vitamin supplements added to
water. I avoid other additives.
My troubles started 1 month after cycling was complete and the Bird wrasse had
been sole occupant. I added a smallish harlequin tusk and keyhole angel (without
dip or quarantine - yes I know now!).
<yikes... yes>
All lived happily and all fish fed very well for about 2.5 weeks then
Amyloodinium struck both the Tuskfish and the angel (both were in the same tank
at the LFS). I started treatment immediately with Quinine Hydrochloride as I
read the tusk were sensitive to copper.
<Hmmm... yes. Agreed. Although quinine is not exactly gentle either>
I didn't fresh water dip because the LFS told me that was worse for the fish.
<they were wrong in my opinion. FW dips are time tested and true. Very
effective for the majority of fishes we keep. And not so toxic and medicants>
Three days later the tusk died. I FW dipped the angel and it recovered and then
succumbed 4 days later.
Anyway I removed the Bird Wrasse (it seemed to get no velvet infection) and let
the tank go fallow for 4 weeks. I added the hermits and stars and a couple of
turbo snails (which have since been eaten by the Bird Wrasse and hermits). After
the 4 weeks I reintroduced the wrasse and added the Corallimorph.
All is well. Two weeks later I added the Sarcophyton. All still well no sign of
disease on the wrasse, so I added 3 blue/green Chromis after dip and 1 week
quarantine. About mid January I added the Lobophytum, Sinularia and BTA. After
some settling in all the corals and the BTA seemed to be doing fine and still
are. About 2 weeks ago I was encouraged by my wife to purchase another harlequin
tusk. It was added after dip and a week in quarantine and feed well from day
one. The next day one of the Chromis appeared not to be able to find food. It
was the smallest and I assumed it was getting bullied by the other fish. It died
about 1 week later obviously from starvation. Everything was fine for another
couple of days until last week. Thursday
afternoon all fish were fine and had a feed. The next morning the Tuskfish and
one of the Chromis were displaying the same behaviour as the smaller Chromis
had. It seems that they are blind and cannot see to eat.
<wow...this is unusual. Blinded commonly occurs from a chemical
agent/treatment or prolonged poor diet. Pathological causes are rare. There are
worms that burrow in the eye and can cause this, but I have never seen them...
only read of them (Untergasser, Post, Noga)>
I have been able to force the Tuskfish to eat. The Tuskfish sits on the bottom
all the time until the wrasse and good Chromis feed, then it rises to the
surface obviously to eat but doesn't and falls back to the bottom of the tank.
There are no obvious signs of disease on either fish. Breathing is not
rapid, still have normal colour. Fins are widespread like in a state of alarm.
Neither fish responds to any movement and bump into objects and the other fish.
I have not been able to find anything to indicate what this may be.
<I would still highly doubt a pathogen is at hand here, rather that a
household toxin got in the water and is wreaking havoc (not 8uncommon for it to
effect fishes or invertebrates but not both). You'd be amazed too how many
common household dangers there are: aluminum from anti-perspirant from your
dipped armpit in the tank, burning a Teflon pan in the house (very dangerous to
pets), paint strippers, aerosol/spray air fresheners in the room... the list
goes on>
I have spoken to one respected LFS here who said HLLE was the only thing they
could think of but normally the fish would have been in captivity for a while.
<HLLE is not even remotely possible as the cause. The onset takes many months
and doesn't cause such/any sudden blindness. I'm worried about your consultant
;) >
They also said I was the 5th customer to report such in the last
couple of weeks.
<all the more reason it is not "group" HLLE... and if true, more
support for the theory of a contaminant... in this case, the only likely common
thread being your tap water. Do call your authority and ask for an analysis and
if they have been adding anything to the water known to be of risk to pet
fishes. Some water authorities for example add aluminum to counter lead in
big/old city plumbing>
The only thing I can come up with is stray voltage. I measured the voltage in my
tank and with all pumps running there is 3.2V discharging into the water.
<ground it... but doubtful>
Do you think this could be the cause or are you aware of any other
likely cause.
<as per above>
I have avoided treating them this fish unnecessarily at this stage. I would
appreciate any comments you may have.
Regards, Ed Jackson
<let me strongly encourage you to begin using buffered, store bought
deionized or RO water... do some large water changes and use Polyfilters (Poly
Bio Marine) o sop up possible toxins. The blindness may very well not be
reversible. Please do keep us posted of developments and progress here. Very
interesting. Anthony>
Unexplained Blindness in Marines II 2/16/04
Thanks for your response Anthony
<always welcome mate>
Before I received your reply, I decided to treat with a general
antibiotic/fungicide as I had the water checked for problems and it came up OK.
So I pulled the tusk out of the main tank and treated with a double dose of
tri-sulfa. I also placed activated carbon in the main filtration system for the
display tank.
After 2 days in the treatment tank the tusks eyes clouded over which I suspected
was the treatment. On the third day his eyes had cleared somewhat. I did a 50%
water change on the treatment tank and administered a standard dose. The fish
seemed to be responding very slowly but still did not eat and refused any food
placed near his mouth. On day 6 his eyes were clear and he was swimming around
instead of just remaining on the bottom. However still refused to eat. Because I
could not keep the water quality up and he appeared to have no other signs of
disease I moved him back to the main tank. When I emptied the treatment tank I
found a small (4mm) oval disk about 1mm thick. It appeared to have a crusty
covering and looked biological because it was symmetrical in its markings. A
small black patch near the centre with three small black lines (0.5mm) radiating
outward on either side of this. I considered this to be the "top"
while under was a paler colour with just the dark centre. I have not been able
to accurately identify this "object" and I don't know if it had/has
any effect on the fishes health.
<very interesting... alas, without a photo or better description I cannot say
either. My guess is that it is unrelated actually>
The day after I moved the tusk back to the main tank he appeared to get a small
infection of Ich (no evidence on the other 2 fish) and started to produce excess
mucous. Eyes clouded over again and fins went cloudy. Geez Louise!!
<yes... 6 days in QT was about 24 days too short ;)>
Another 3 days passed temp in the tank has been steady at 28c and the fish has
not changed behaviour or symptoms and has not eaten for 2 weeks. So I decided to
do something completely out of left field and with no real point other than I
guess to "do something".
I purchased and installed a UV sterilizer. It has been running 2.5 days,
<do know for this unit to work properly in the long run the water must always
be crystal clear (daily ozone use and/or weekly changes of carbon) and the
incoming water to the UV has to be highly polished mechanically. Else the unit
will fail to be effective in mere weeks>
and this morning the tusk is clear of any spots, fins are clear and he was out
looking for food. I was able to get him to take a chunk of marine dinner. The
first food now for over 2 weeks.
<outstanding!>
Although he still seems to partially blind he is responding to movement from one
eye and doesn't bump into things or the other fish anymore. I realize the lack
of white spot could be the result of the parasitic lifecycle but here's hoping
that he continues to improve. The interesting thing in this is that I have been
to 2 other LFS in the last 3 days and each time I heard them talking to someone
about fish not being able to find food but didn't have any outward signs of
disease. In both cases the staff discounted the stories and said they must have
Ich or
Velvet or some other disease.
<I agree with you.. very odd>
Water supply or pathogen, wish I knew. Thanks for your help.
Regards Ed Jackson
<thanks kindly for the update... much appreciated! Wishing a fast recovery
for your charges. Anthony>
HLLE or Injury?
Hey guys, thanks for taking time out of your weekend to respond so quickly!
<That's why we're here! Scott F. back with you again today>
Unfortunately, the Orchid Dottyback died in the quarantine tank. Looking at the corpse, it looks like it was due to injury, probably from zipping around during capture at the LFS. :-( Luckily, they were very nice and have ordered me a free replacement which they will keep isolated from the main
tanks (the other one they had was too badly injured to survive long).
<That IS nice of them!>
I have another question though... I just got back from work today to find that my Coral Beauty Angel has what looks like a large yellowish-pink scrape down his "forehead". The strange thing is there is a very small yellowish-pink scrape looking mark on his "cheek" too. About a week ago I noticed what seemed to be a whitish loose scale on his side. I kept an eye on it to make sure it didn't turn out to be a parasite of some kind, and it got smaller and went away over the next few days. I thought nothing of
it, but with the appearance of these new marks I'm beginning to get suspicious that he may either have a disease of some kind or he may be getting harassed by my Yellowstripe Maroon Clownfishes for some reason and getting injured.
<All valid concerns and well worth checking out. You also may want to consider that
this is the beginnings of Head and Lateral Line Erosion (HLLE), which is thought to be a dietary and/or environmental disorder, in which the head of the fish appears to have tissue "eroded" away in a manner similar to what you're describing. The disease does not appear fatal, and indeed may be reversible with positive environmental manipulation and use of vitamin enriched foods of high quality, including fresh seafoods and algae...Do review the material on this condition here on WWM and elsewhere...>
Here's my tank setup:
46-gallon bowfront
65 lbs. live rock
4" deep sand bed (which is working awesomely)
CPR BakPak IIR Skimmer
192w PC Lighting
2 Yellowstripe Maroon Clownfish
1 Coral Beauty Angelfish
1 Tiger Watchman Goby (Valenciennea wardi)
1 6" Bubbletip Anemone
1 Fire Shrimp
1 Scarlet Skunk Cleaner Shrimp
Various hermit crabs and snails
SPG 1.025
Temp 80
Nitrites 0
Nitrates 0 (love that DSB)
PH 8.3
Hardness 425
Alk 260
Weekly 10% water changes
I have noticed the female maroon "cleaning" the sand in one spot by fanning it with her tail lately, maybe a sign of mating, but I haven't seen either maroon act in any way aggressive toward the coral beauty. There have never been any problems with him and the BTA either. I just added the goby from quarantine, but it doesn't seem like that should cause any problems. I'm hoping he just got scraped on the live rock, but I wanted to find out if there are any diseases or parasites that look like this. He's very active as
usual, and eats like a horse. Thanks for your help guys!
Jarin
<Well, Jarin, sounds like either an injury or the aforementioned HLLE condition. Look into both, keep up the good work, and take any action that is necessary! Good luck! Regards, Scott F>
Bloated Beauty (2/2/04)
I'm resending this b/c my images were too large, sorry for that! <No
problem.>
Hi all, <Steve Allen tonight.>
You guys and gals have been so helpful in the past now I am calling upon your
expertise for a fish I believe is at risk. I have a Coral Beauty that has become
excessively fat (bloated) over the past couple of days. <Yikes. Does look
very uncomfortable.> He/She is in QT and has been for the last week; in which
I have lowered the salinity from 35ppt to 17ppt, I was going to go down to 14ppt
tonight but "alarm" my prize fish is in trouble. <Is he in the QT
for this or for something previous?> This coral beauty is ~5 years old and
was big before the bloating but now it is enormous and looks like it is having
trouble breathing. I have attached some pictures so you can see the girth.
Should I add Epsom salt, or do I need something else. Thanks in advance from me
and the fish. - Ryan
<Epsom salt is helpful for simple constipation. Lowering salinity is good for
external parasites, but not internal. What is the purpose of your hyposalinity
treatment? I'd be a bit worried about internal parasites or even a tumor.
Consider treating with an antihelminthic. You may even want to consult an exotic
animal vet in your area. Is the fish pooping? What is the poop like? I think
that saving this fish is going to be an ongoing, intensive-care process. I
recommend that you start a thread in the 911 forum at www.wetwebfotos.com to
seek input from a number of experienced aquarists. You can more easily maintain
an up-to-the-minute dialogue there. A lot of great folks there would love to
help. I'll follow along there too. Hope this helps. Steve Allen>
Net pictures of diseases
Do you know of any website or maybe yours that have detailed pictures of
common diseases in a marine setup? Not that I currently have a
problem with
any of them (Knock on wood), but I just want some pictures in case I ever
come across any. Thank you for your time. Scott
<No complete ones/coverage as far as I'm aware. There are some excellent
books on the subject. I use Edward Noga... you can look him up on Amazon.com or
elsewhere... we have image work of some of the major marine biological diseases
on WetWebMedia.com. Bob Fenner>

Mysterious Fish Deaths-The Truth Is Out There...
Hello again,
<Hi there! Scott F. with you>
I have attached a couple of photos taken of my Naso and yellow hours before they
died. The suspicious thing about this is the loss of such a healthy Naso and
yellow along with three yellow tail damsels and not a hippo tang or coral
beauty???
<Hmm...Lots of possible causes, ranging from a toxin in the water, to some
other kind of environmental trauma, or even a sudden onset of a parasitic
illness>
One LFS suggests that it appears to be a mucus deficiency but could not suggest
a cause. Your opinion would be greatly valued so I know what to do with the tank
from here on. My inverts and tank overall appears to be very healthy, making me
discount water conditions for the most part. The only dosing is 1/2 of one
teaspoon of Seachem Kalk premixed in 1400ml of water and does in a Kent drip
bottle just after lights out every other night. and a couple of drops of Iodine
every couple of weeks.
If the attachments are a problem please advise how you would prefer to receive
them??
<The attachments were fine. It was kind of hard to tell what the problem may
have been, based strictly on the pics. Since you indicate that the environment
has been stable and acceptable, and since the inverts are doing well, I may be
inclined to think that you're looking at a possible virulent disease- perhaps
Amyloodinium, which strikes suddenly and kills quickly...On the other hand, your
fishes did not seem to have any detectable symptoms, right? This is indeed a
mystery. My advice is to do a complete test of all major water factors. If
things look fine (as I suspect that they do), then you may want to consider a
toxic substance at work, contaminated food, an electric shock, who knows? It's
not funny, but it is tricky to sort out. Try looking at the obvious, and then go
from there, considering even the bizarre...Hopefully, your search will locate
the answer...Good luck! Regards, Scott F>
Thanks once again
Rob

Re: Sick Tank (follow up) 12/14/03
Thanks Adam for your response. Things are better now, lost only one fish.
<Glad losses were minimal>
Thanks for the tip on stray voltage I will check that out.
<I do recommend that you do.>
Still a mystery as to what caused all the trouble.
<This is so often the case, even with very seasoned aquarists.>
Today some green film was back on glass
(absent throughout ordeal) so I think I'm back to normal.
<This is probably algae growing in response to the newly available nutrients. I
do urge you to remain aggressive with water changes at least for a couple of
more weeks just to be safe.>
Again Thank you all for your hard work. Without WWM I'm not sure I would still
be in this wonderful hobby.
<Glad to help. WWM helped keep me in the hobby way back when too! Adam>
