Black Itch on Yellow Tang?
8/29/08
G’day Bob,
<AJ>
I’m unsure what's wrong with my Yellow tang. It has a small cluster of very
small black spots on its right side half way down the body. They don’t seem to
bother it and haven’t spread either I’ve noticed them there for about 2 months
he/she doesn’t scratch either. At the moment it’s in a QT tanks and I’ve treated
2 x with Paracide and 1 x with Trisulfa tablets + 2 x freshwater dips and the
cluster is still there. What could it be please? The fish eats well and is in no
distress.
Thanks
AJ
<Mmm... is very likely Paravortex... Read here:

and the linked files above. Easily treated... not very debilitating... Read. Bob

Praziquantel and Paravortex
- 7/1/08
Morning crew,
<Good morrow to you>
I suspect my yellow tang may have developed black ich.
<Developed...>
With its classification as a Paravortex, a Turbellarian worm, would Praziquantel
be a suitable remedy?
<Mmm, unnecessary but yes...>
I understand that a freshwater dip is also recommended, but would Praziquantel
have better effects of eradicating the Paravortex life cycle in the tank itself?
Thanks, Brian
<Likely so... though time going by w/o host/s almost always "does it"... You
have read on WWM re? Bob Fenner>
Black Ich Yellow tang 5/30/08
Hello Crew
<Wayne>
I've read a good portion of your FAQs on Black Ich. While I've learned a lot,
I'm still seeking your advice. I don't want to over react. If you read on about
my QT problems, hopefully you'll understand why I'm hesitant to QT my Tang.
My tank is a 210, with 220 lbs of LR. I have 7 Green Chromis, 2 Firefish, 2
Scarlet Cleaner Shrimps, 5 Peppermint Shrimp, a few crabs and snails, Frogspawn
and green star polyps. The tank has been up and running for about 3 months now.
<Not long...>
I just added the Tang after 2 weeks in QT (more on this later). He's been in the
display for 1 week. Yesterday I noticed 8-10 black spots that seem consistent
with Black Ich. It's a really subtle infestation at this point.
<Paravortex is... sublime>
My Water params are good. Temp is very consistent @ 80, Ammonia, Nitrites are
zero, nitrates are 2-5 ppm. I do weekly 20% water changes using RODI water.
Salinity is 1.025. Ph is always low...usually 7.9 - 8.0. I'm working on this.
The Tang has just started (yesterday) to use the cleaner shrimps. It's so neat
to watch. Should I be QT'ing this fish?
<Mmm, no. I wouldn't>
Or should I wait it out?
<Yes...>
Maybe some good nutrition, time to settle in the display, and help from the
cleaner shrimps will clear this mild infestation?
<Yes and this turbellarain is not "that" debilitating>
I feed a mixture of foods (formula 1 and 2, green and red seaweed, mysis shrimp,
Spirulina brine shrimp/flake food, and a modified Eric Borneman recipe).
The tang eats all readily. I do plan on adding a Powder Blue, and Hippo Tang
down the road.
<After a few more months at least>
I'm hesitant to QT this fish as I have a hard time maintaining good water params
in QT. The reason he was only in QT for 2 weeks, was that I couldn't keep up
with water changes. I have a 28gal that I use for QT. I use a sponge filter with
sponges that have been seeded in my sump for more than 6 weeks. I can't keep
nitrites down. I have always had problems keeping up with water changes in QT
tanks. I was doing 15 gal water changes daily, and that wasn't enough. This is
nothing new, I've had other tanks in the past, and have always had problems
keeping Ammonia and Nitrites down.
<Yes. Typical challenges>
What would you do? FW dip and Qt this fish, or give it a chance in the display?
<This last>
Also, just want to confirm that this parasite won't infest my Chromis and
Firefish.
<Not likely>
This parasite exclusively feeds on Tangs correct?
<Mmm, no... has been found on other families>
So without a tang in the display, the life cycle will be disrupted. Am I
correct?
<Yes, usually... but can take months to die out>
Thanks again for all your help! Don't know what I'd do without the Crew!
Wayne
<I'd proceed as you are now... not worry re. Likely the worms will be consumed
by the cleaner shrimp. Cheers, Bob Fenner>
Re: Black Ich Yellow tang 05/30/08
Thanks for your prompt reply Bob. Just a few questions pertaining to adding the
Powder blue and Hippo Tang. You say not to add them for "a few more months at
least." Should I wait a few months after there are no more spots on my Yellow
tang? Or are you saying to wait a few more months because my tank is young.
<The latter>
Is the idea to not add any fish until my tang is completely spot free? I fear he
might always have a few spots on him...and if that's the case, I'll have to QT
at one point or another.
Thanks again Bob/Crew!

Black Ich??? 12/10/07
Hi Bob,
<Lane>
I purchased a Powder Brown Tang about 6 weeks ago. I placed the tang in
QT and treated with Cupramine for a week as preventative for ich. The
fish also had a few black spots which I thought might be black ich.
<Appears to be so>
I hoped the copper would help with this as well,
<Ah, no. If anything, would hurt the host...>
but it did not appear to do anything. After week one I replaced all the
water in QT and did a FW dip.
<For how long?>
I thought it may take a few days for the spots to go away, but after
several days of observation the tang appeared to be getting a few more
spots. I did another FW dip this time with Methylene blue. Once again it
did not seem to help. I then decided to try Prazi Pro treatment. After
about one week I still did not see any improvement,
<Wow!>
so I decided to do another FW dip and then try treating with Rid-Ich
(malachite green and formalin) in the QT.
<Yikes>
After several days the spots still remained but the fish appeared to be
getting fin rot and what appeared to be stressed breathing.
<I can imagine>
I decided to do a 100% water change and another FW dip with Methylene
blue. After several days the fish was healing nicely from the fin rot,
but still has the dreaded black spots. I decided once again to try
treating with Prazi again, but this time I increased the dosage from 2.5
mg/l to around 4 mg/l. It has been a week and I am still not seeing any
signs of improvement.
<Very strange indeed>
The spots seem a little more pronounced than before, but the fish does
not scratch or seem overly affected. The fish loves algae and is eating
tons.
<Good>
The biggest thing is the fish has a very pale body (semi-transparent).
Is this something other than black ich?
<Can't tell w/o microscopic examination>
How can I get rid of this?
<What you've done should have...>
I really want to save this fish and really want to get it into my
display tank. Your thoughts and suggestions are greatly appreciated. I
have attached a picture for you. Please disregard the white spots as
they are just bubbles. Thanks again.
Lane
<Mmm, a decision (as in nothing is decided until it is done) needs to be
made... whether to try re-doing a treatment regimen (if it were me, with
another source of Praziquantel or other vermifuge, see WWM) OR just
placing the Acanthurus japonicus directly in your display... in the hope
that the (likely) Paravortex will cycle off in time, not infest other
fishes there (not all are susceptible)... Which will you choose? Bob
Fenner>
Re: Invincible Black
Ich??? 12/11/07
Bob,
<Lane>
Thank you for the input. Just to answer your question, the dips were
approx. 10 minutes.
<Gosh... these should have "done it"...>
Anyway, you recommended a different Prazi treatment or placing the fish
in the display tank and hoping for the best. I don't want to do this as
I have a yellow tank
<Tang I'll take it...>
as well. I would feel much better keep my display free of issues.
<I see>
What do you think about Jungle Buddies Parasite Clear. It contains
Active ingredients: Praziquantel; N-[[(N-Chlorophenyl) amino] carbon
1]-2,6-difluorobenzamide; Metronidazole; Acriflavine - Water ???
<The last as a carrier/diluent... I do think this product would work as
well>
It sounds reasonable, but I does not say anything about saltwater
Compatibility. Thanks again.
<All the ingredients are fine for use in seawater... NOT in your main
system though. BobF> |
