New question about an old
issue, shark hlth., sys. 4/26/08
Crew,
<Tom>
Perhaps you remember (and perhaps you don't) me writing a ton about a pet Banded
Cat Shark that I owned, my display tank having ick with the shark, and my
treating the tank with Quinine Sulfate in an attempt to eradicate the ick with
the shark present. And you might remember how the Quinine was very effective in
ridding the tank of the ick, but that the shark began a steady decline over the
course of a month and a half and finally passing away after being unable to eat
(this after feeding wonderfully on shark formula and vitamins for 6 months, and
doing quite well.)
<I do recall>
Months have passed, and though I have added a few additions to the tank, we have
been nearly 4 months with absolutely no issues. But, my mind still wanders back
to that time and while I have no intentions or desire to have another shark, I
still think about what caused his demise.
I don't really run carbon continuously in my tank. It's 200 gallons with
probably 150lb of live rock, filtered by a Fluval FX5 (which I clean and rinse
sponges every two weeks) used mainly for water flow and biological filtration, a
wet/dry trickle filter, and a large hang on protein skimmer which is actually
rated for 180 gallons. I do a 25% water change every two weeks. But I do have a
small canister filter that I put carbon in and run on occasion. Obviously during
the treatment with the Quinine, I did not run the skimmer or the carbon. but
after the treatment duration I did appropriate water changes, turned on the
skimmer and put carbon back on the tank. Now, I wonder, how long is fresh carbon
actually viable?
<Mostly gets "used up" within minutes, hours... rapidly drops off past then>
Some information outlets say change it every couple of weeks. but some say the
most effective use of new carbon is in the first couple of days. being that this
canister filter isn't large to begin with, do you think that it was not
effective at removing all of this quinine, and the lingering presence of this
medicine caused the shark's demise?
<I do not>
Water parameters were the same then as now, salinity was 1.025, PH was 8.2, 0ppm
of both ammonia and nitrites, nitrates less than 10 - 20 ppm at all times.
Again, no problems to resolve now, but something that bugs me and as I think
about it often, I might have new questions about it.
The tank now houses a 5" Passer angel, a 6" Lunare wrasse, a 5" yellow tang, a
Maroon Clown, and a Snowflake Moray. All have been problem free nearly all of
2008.
Thanks so much.

shark selection -04/11/08
hello.
i am currently thinking about getting a shark. i have decided on 3 different
sharks. then white spotted bamboo, gray bamboo, and my fave. the swell shark. so
my question is what size tank will the swell shark need? i would be getting a
240 most likely. would that be able to home a swell shark? i have read that is
enough for a white and gray bamboo. thanks for your help!
<240g is probably the bare minimum. There's lots of reading to do. Please start
here:

Hey just wondering which size will best suit a swell shark.
60x36x25 240g
72x30x25 240g
48x48x25 240g
280 - Wide
72 x 36 x 25 Tall
300 Wide
96 x 30 x 25 Tall
Obviously I wanna save money to the 240s are cheaper but when talking
for the shark should I just go with the 280/300 ? I want him to be
happy.
<None of these tanks are big enough for a swell shark (Cephaloscyllium
ventriosum), which reaches 3 feet in length. To be honest, if cost is a
consideration you should skip owning a shark.>

My question is, is a 240 gallon tank big enough for a swell shark or
not?
<Not for its full life span in my opinion/?
One of you said yes one said no.
<Opinions differ.>
And which of those dimensions would be best for my shark.

Chris one of your workers said 240 or ever 300 is not big enough for a

While I believe it was Sara said 240gallon would be the bare
minimum...so which is it????
<A 240 would work for a while, but not even close to the entire lifespan
of this shark, and good luck getting rid of an 18 inch shark when it
needs a good home. I believe this is what Sara was trying to say when
she said bare minimum.>
Also I had a list of different dimensions that I was wondering which
ones would be best. which I have posted below thanks.
60x36x25 240g
72x30x25 240g
48x48x25 240g
72x36x25 280g
96x36x25 300g
I obviously want to save money yet I want my shark to be happy so which
would be best?
<The shark may survive in any of these for a while but not thrive.
That’s all a bare minimum system will allow it to do. Also sharks are
very expensive to keep, it the price difference between a 240 and 300 is
enough to make a difference you should probably try keeping less
demanding animals.>

Coral Catshark breathing a
little fast and keeps swimming to top of tank... Reading...
2/27/08
Hi, I just purchased a 18 inches coral Catshark today. While I was
acclimating him he kept swimming around the foam bucket.
<I hope you had "heavy" aeration going on during...>
After an hour I put him in the tank 150 gallon tank.
<... too small a volume>
After about 10 minutes he starts swimming around like crazy going up to the top
of tank. He would do this and then go back down for
a while. I checked the water before I bought him and everything was at 0 and the
salinity was .025.
<... no>
The store owner did tell me his water salinity is .016.
<!? Much too different...>
He also said the only thing he fed him was silversides.
<... a very poor diet>
Do you think that's the reason.
<Reason for?>
He fed him before I bought him so I can see he eats. He said he had him for
about 5 months. Oh I have a vtail grouper 5 inches and a Miniatus
grouper 4 inches. I unplugged the heater out of the sump and took the glass
cleaner out of the tank and the thermometer out. I have some live shrimp in the
tank but he doesn't try to eat them. I have a uv, protein skimmer, wet dry/sump.
Should I buy a pump for more air. I don't want him to die, what can I do to save
him. Did I do something wrong ? Please help

Shark tank... maybe not
– 1/04/08
Hi Bob,
<Max>
I have loved the ocean and fish my whole life and kept many marine tanks and
small Elasmobranchs (brown banded bamboo and epaulette) and now I am going to
build a home large enough for a mini-mega ?shark tank? in my living room. The
tank that would be built is an 8945 gallon custom aquarium with an FRP shell,
the dimensions are 20? x 10? x 5? w/ a bullnose on one end bringing the total
length to 25?. I'm thinking about acquiring leopard sharks and/or grey
Smoothhounds (I would chill the water and keep only cool water fish in the
tank), or black tip reef(s) and bonnetheads or white tip(s). I would love to
have a zebra shark but the tank would simply be too small. Any other good
specimens (sharks or rays) you can recommend for a tank like this?
<Mmm, do you mind if we "step back" a bit here? Might I ask if you've calculated
the cost of operation of this system? How much electricity to run the pumps,
chillers? What sort of chilling mechanism do you intend to employ? Am hoping to
help you understand, or you to help me understand that you know what's entailed
here... Triakis and Stegostomas are going to spend most of the time setting on
the bottom...>
Does this sound good, or sound ethical (by aquarium standards, nothing compares
with the ocean)?
<Don't see enough data to make such a judgment call>
-Max
P.S.,
I have been doing a lot of research on the zebra sharks and made a discovery
that in captivity they rarely exceed 8? in length. True?
<Stegostoma fasciatum? I guess this is correct...>
If true I was wondering if I instead increased the width to 14? (total of 13343
gallons) if it would be sufficient enough to house one?
<For several years, likely so>
If false then I will just completely scratch the idea of keeping one and instead
visit them at an Aquarium.
<FWIW, I would take up diving... put the money it's going to take to build out
and maintain this system into dive/adventure travel... and go see these
Chondrichthyans in the wild... Yes... I AM encouraging you to come
dive-traveling... with me/us! Bob Fenner>
Re: shark tank 1/5/08
Hey again,
<Max>
I also love to snorkel. I cant dive due to ear problems though :(. I
usually go to Hawaii and right here off the La Jolla coast.
<Ahh! I/we live in "East La Jolla" (okay... Mira Mesa) here in San Diego
as well>
Anyways to the point, the cost of the tank installation would be around
$250,000 - $300,000. this includes all the filtration. For the chiller I
would be going with an AquaLogic 18000 BTU chiller (seems kind of small)
<This is... there is much better technology... look to a company to help
you with a heat exchanger, diffusion mechanism... of size>
or possibly an AquaLogic heat pump (heats and chills). And for the
monthly costs am figuring around $2000 - $4000,
<Likely about this>
but am taking into consideration to use wind power (or something
similar) to help cut down on the monthly costs. Am also going to get
generators incase of a power outage so I can run the filters to ensure
their safety (if I do indeed get the tank).
Also, I have decided to not make the tank bigger and not to get a zebra
shark.
-Max
<Nice dreams. BobF>
Re: shark tank 1/5/08
Thank you for all of the good advice and thoughts. And I'll definitely
be sure to do some more research on the chillers/heat pumps.
-Max
<And pumps period, the mechanicals involved here Max... One can drive
themselves into the proverbial poor-house w/o sufficient
investigation... You WANT multiple phase pumps, skimmer/s of size... Are
you familiar with RK2 products? Of all the luck, they're located here in
San Diego! See their new website: http://www.rk2.com/
Robert and Chris Krechter have VAST experience in fabrication,
installation of mechanicals and controllers for projects as yours. Call
them. Bob Fenner>
Re: shark tank 1/5/08
Hey Bob sorry to bother you again,
<Not a bother>
I did some more research on the chillers. I have found a 120000 BTU
chiller by AquaLogic and a 180000 BTU by AquaLogic.
Do you think one these would fit the bill? Or would you step up to the
240000 BTU?
<Neither... do call the Krechters...>
Thanks again,
Max

Sharks in my living room?
Sys... 12/16/07
Hello, I am only writing you because I have found an error in the article
Sharks in My Living Room? located at http://www.wetwebmedia.com/sharkslvgrm.htm.
I would like to point out first off, that I have on the second floor in my house
in my room a 75 gallon saltwater reef tank, and a 220 gallon shark tank housing
one brown banded bamboo shark. So if we used the 8lbs per gallon calculation
that would put 2360lbs worth of water in my bedroom on the second floor. They've
been setup for a year with no problems.
<Unfortunately, there are many marine animals which can take over a year to die.
And even if the sad creature doesn't die, as Steven Pro is quoted as saying "I
could stuff you in your closet; if I fed you and provided you with air and light
you would live. But would you be happy?”>
Also the article says, "One other thing to consider, even if you have no
basement; is that even with only water, the weight of the tank is equivalent to
putting a Dodge Ram 1500 in your living room." Right before that in the article
it says that a 220 gallon tank only
water would weigh 1760lbs. A Dodge Ram 1500 weighs in with a curb weight of
roughly 6600lbs.
<Really? I thought it was closer to 6400lbs... hmmm, maybe that's with only half
a tank of gas?>
That would be the equivalent of a 825 gallon tank,
<...which would be a more appropriate housing for a shark.>
not a 220 gallon. So it can definitely be done,
<It can be done, but done well? I could build a house out of popsicle sticks,
but would you want to live in it?>
if your house is structurally sound, to have a shark tank in your second floor
bedroom. By the way the shark is doing great and appears to be very healthy for
about a year now!
Thanks
<Thank you for pointing out the flaw in Mr. Bozek's analogy. Perhaps he was
thinking of the weight of a closer-to-ideal tank set-up rather than just the
bare minimum to keep the animals just short of death.>
Greg
<Best,
Sara M.>
Re: Sharks in my living room?
Militant stupidity, insults in general... unexpurgated -12/16/2007
I'm so sorry, thanks for being a total bitch.
<I do regret that you were hurt/offended by my candidness.>
I forgot no matter what you all are always right and know more than god.
<?!>
I will go return all of my fish and aquatic creatures to the ocean where they
can THRIVE in the correct amount of water for them.
<Please don't do that. Returning pet animals to the wild (after they've been
living in an uncontrolled captive environment) is quite irresponsible.>
I also will return my German shepard to the wild, because I am sure she is not
happy with the amount of land I have to let her run around.
<Hmmm... this is not an appropriate or intelligent analogy. Domesticated dogs
have evolved (been bred) to a life in the company of human beings. However,
still Steven Pro's words might be applied here... would you keep your German
Shepard in a closet?>
I also will let my cat go free so she can run and get the exercise that she
REALLY NEEDS.
<See above... domesticated cats have also been bred to a life in our company.
However, I do hope she is getting some exercise and mental stimulation running
around your house and/or playing with you and yours.>
Oh almost forgot I'll let my 2 rabbits out into the forest so they can make a
suitable home for themselves and can eat the proper food and be in their PROPER
HABITAT.
<Hmm... rabbits are pretty low maintenance animals. You probably could keep them
in a closet (though I wouldn't recommend it).>
If you all want to get so incredibly technical
<Incredibly technical? ...seriously?>
about what species of fish needs what size tank to live correctly your all
wrong. EVERY fish needs the OCEAN to thrive,
<There's a HUGE different between the ocean and a ~200g tank! Sharks can and are
kept well in many large public aquariums (and even some exceptionally large home
aquariums). Sure, it's not the ocean, but sharks can be kept well in captivity
(just not so well by hobby aquarists in 200g tanks).>
so I guess we are all just assholes that take living creatures from their homes
and lock them up in our glass jail houses, feeding them only enough to live and
providing them with only enough water so they can swim in circles.
<It is/would be cruel to do this. And this is why I/we recommend better
accommodations. True, we can't provide them with the whole ocean in our living
rooms, but we can try to give them enough that they are at least "content" if we
can't give them enough to thrive (which is even better).>
So after I am done sending this, I will take a trip and put everything back into
the wild so now
<Please, please don't do this! It's quite irresponsible and likely illegal.>
you and the entire crew at WWM can be incredibly happy and can sleep soundly
knowing that all of the precious fish are happy, because I forgot I don't know
when they are healthy, only you do.
<::sigh:: My dear fellow aquarist and human being, please do take a moment to
reconsider your attitude/tone here. Intelligent people can disagree and still be
civil. I'll leave you with these words from William Shakespeare: "Do as
adversaries in law, strive mightily; but eat and drink as friends."
Best,
Sara M.>

Shark pond... sys., and stock
sel., reading – 10/30/2007
Hello,
<Hi there>
Long time reader, 1st time I've written. Thanks in advance for your time /
advice.
<Welcome>
I've argued, reasoned and walked away from people who wanted me to help them
setup a 200 gallon shark tank, but for the first time have a customer that
presents a possibility that just might work. I have a great deal of reef and
FOWLR experience but I've never owned, sold, or cared for a shark.
The pond was to have been for Koi, now he is thinking saltwater and sharks /
rays. The system will be just under 1600 gallons, 24 ft long, 3.5 ft wide and
2.5 ft deep. It is best described as a cement "tray" which will be tiled on the
sides and have a substrate of our choosing on the bottom.
This "pond" will be indoors, we could include a very large chiller, but I would
rather stick with animals that will do well in the area of 75 degrees.
<There are many>
Filtration will be a skimmer, something big, though we will have some kind of
height limit. Something like this:
http://www.championlighting.com/product.php?productid=21017
<http://www.championlighting.com/product.php?productid=21017&cat=646&pag
e=1> &cat=646&page=1 or bigger / better if possible.
<Okay... though I would write RK2, EuroReef... look into something "larger" in
terms of function here>
Everything I read simply suggests a "large" tank and at least 3 * the animals
length. I would like to keep everyone as small as possible.
Under 30, maybe 36 inches have a bit of variety in the animals and stick with
hardy, easy inhabitants. I am worried about the width of the pond and larger
fish being able to make the turn.
What combo of sharks, rays, eels and anything else would you suggest?

I also have a question on
keeping sharks, sys.
Hello again Bob
<Todd>
I also have a question on keeping sharks. I have always wanted to have a shark
tank since I purchased my first marine book (one of yours of course), but have
never had a aquarium large enough for even the smallest ones. I have a 120 now
and never wanted to get a fish and give it away after I became attached just
because it outgrew the aquarium. I would like to set up another aquarium for 2
brown banded bamboo sharks and two other larger fish. I have read a million
times you need to have like a 12' L x 4' W x 2' T aquarium minimum for them to
be ok and happy as adults. Is a tank that size needed more for room to swim then
water volume?
<Mmm, space to move, provide gas exchange, dilution of wastes... stability
chemically, physically>
I also have read that a cylinder aquarium is the best kind of aquarium you can
get for sharks because there's no corners.
<Well, one with rounded corners for "sharky" sharks... but ones that laze about
the bottom most the time, like the Epaulettes, Bamboos... not really>
Would a 4' to 5' W x 2' T cylinder be ok for the two bamboos and the two others
or would I need to go larger for adult bamboos, if so how wide?
<Would be better if more oval shaped... a good eight feet long... three or more
feet wide...>
I will have a 150 gallon sump with excellent filtration, water quality and water
movement for which ever tank I end up setting up. Would the sharks be better off
in the huge rectangle or the smaller cylinder?
<The former>
I can get a 48" X 24" cylinder now for a really good deal, and have heard that's
big enough, but I think at least 60" or even 72" would be needed.
<I agree>
Or should I stick to Sea World, Shedd aquarium, Blue Planet and Shark Week!?!?
<Oh! Was watching a segment of the Blue Planet last night... Spectacular
footage.>
Thanks again for the info!!!! Todd

Banded Cat Shark - Some
Questions... too small sys., BGA control, using WWM
8/30/07
Mr. Fenner (and crew),
<Etay>
first I would like to say that I accidentally stumbled on you're site while
searching for some background info on the banded cat shark and found it loaded
with important and viral
<Heee!>
information. I since then read other FAQ's and marked this site as I feel I will
return to it often !!
<Okay!>
ill start with some background info before the questions :)
I have a 100 gallon reef tank, currently housing:
lg. coral banded shrimp ( separated due to super friken aggressive dude and
killing all my fish all the time!! )
<CBS can be this way>
Copperband butterfly (med)
tomato clown (lg)
blue devil damsel ( only one left because of the damn shrimp )
yellow damsel
various cleaning inverts.
filtration:
3 inch high live sand bed
<Mmm, should be more or less... see WWM re>
red sea Berlin turbo skimmer
12W UV unit
10Gal sump containing everything w/ some bioballs under skimmer return Magnum
Canister ( broke a leak 2 weeks ago, need to replace with a red sea Oceanclear )
latest tests (yesterday):
SPG: 1.023
pH: 8.2
NH3: 0.0
HO2: 0.0
NO3: < 0.2
Cu: < 0.5 mg/L
<I hope so... should be zip, zero, nada>
Alk: 3.5 mEq/L ( 175 ppm CaCO3 )
tank conditions are usually stable, I perform monthly 25% changes and rarely
check water for anything more the spg and pH unless there are visible issues.
I have had a banded cat shark long ago (~6years), when I was still in Israel,
unfortunately at the time I was totally unaware of the sharks sensitivity to
electrical currents and I guess that caused it to get really unwell and
eventually die :( it exhibited symptoms of sporadic twitching and laying on its
back on the bottom of the tank... Israeli electricity runs 220VAC and not
110VAC, which may have increased the problem even more...
<May be...>
After that I figured I should not try again, I have been diving since age 15 and
have seen other sharks in nature, I feel these beautiful animals should not be
captured for display by those who are incapable of caring for them, I certainly
was not.
<We are in agreement>
That said, last week when visiting the fish store I saw he had a newly hatched
banded cat shark and he mentioned the egg was there for 4 weeks now and no one
got it.. I was hesitating for a while because I feel my tank is much more
suitable than the store and the animal will die there eventually... Eventually I
decided to get the shark
<Not to go in the 100 detailed above I hope>
and with it all that I could think I need;
- I got the grounding probe which I so needed last time! (and good that I did,
before installing I checked the water against ground - 35VAC!! )
<Mmm, where is this stray voltage coming from? I would systematically unplug all
items... check their polarity, assure that they are all wired through a GFCI...
before running the tank another day>
- I got fresh squid and shrimp but have not yet made feeding attempt - the
animal hatched 3 days ago, I figured ill give it till end of week to
acclimate...
- after reading your FAQ I will be ordering the supplement tablets you use.
<Mazuri likely>
I am aware of the fact this tank is way to
<too>
small for this shark,
<So... what are you going to do?>
I have little rock arranged in a center island form so at this size it can still
circle it on the sand and have several caves to go under. Me and my wife are
planning to buy a house this year and I am planning to install an in-wall
300-400gallon aquarium, which should be more than sufficient. if this does not
happen and the shark gets too big to start getting abrasions by rock I will have
to donate it to the NY aquarium or anywhere else it can be cared for...
<... will likely be too late... all too common circular "logic">
so, as to my questions:
1. I have never medicated my tank at any circumstance, I feel if a fish gets
ick, lack of stress and good environment is the best I can do, if it does not
survive I feel bad but I do not want copper traces or any other thing that can
hit my corals ( mushrooms only really ) to be in the tank. I have recently got
some red slime growing in my tank and was wondering if the UltraLife red slime
remover is a reef safe as claimed
<No...>
and more important shark safe and if I can safely use it to remove the red
slime.
<No... and what happened to your laissez-faire attitude re disease above? I
would investigate causes and fix them...>
the seller argued it is antibiotics mostly and should not harm any reef animals
but I am not convinced.
<... Please read both: http://www.wetwebmedia.com/maralgcidefaqs.htm
and: http://www.wetwebmedia.com/bluegralgae.htm
and the linked files above... The chemical trtmt. is very likely to result in
the loss of all livestock>
2. I have not been testing my tank as extensively as yesterday unless something
shows signs of trouble, should I be keeping more close tabs at readings with
this animal?
<Oh yes>
3. how do you know if its a boy or girl? :)
<Posted... the presence/absence of claspers...>
4. how after to feed? last time I was offering every day, the shark would eat
but not everyday, but always by morning it was gone somewhere...
wondering if this is not too much?
<posted and posted and...>
5. any additions/changes to the filtration systems I should be thinking of?
any special concerns when planning the filtration system for the new planned
tank?
mainly I wanted to know about the red slime remover...
tanks for all the helpful info!!
regards,

Mr. Fenner, some comments below...
Subject: Fwd: Banded Cat Shark - Some Questions... too small sys., BGA control,
using WWM
Mr. Fenner (and crew),
<Etay>
first I would like to say that I *accidentally* stumbled on your site while
searching for some background info on the banded cat shark and found it loaded
with important and viral
<Heee!>
information. I since then read other FAQ's and marked this site as I feel I will
return to it often !!
<Okay!>
ill start with some background info before the questions :)
I have a 100 gallon reef tank, currently housing:
lg. coral banded shrimp ( *separated* due to super friken *aggressive* dude and
killing all my fish all the time!! )
<CBS can be this way>
Copperband butterfly (med)
tomato clown (lg)
blue devil damsel ( only one left because of the damn shrimp )
yellow damsel
various cleaning inverts.
*filtration*:
3 inch high live sand bed
<Mmm, should be more or less... see WWM re>
red sea Berlin turbo skimmer
12W UV unit
10Gal sump containing everything w/ some *bio balls* under skimmer return Magnum
Canister ( broke a leak 2 weeks ago, need to replace with a red sea OceanClear )
latest tests (yesterday):
SPG: 1.023
pH: 8.2
NH3: 0.0
HO2: 0.0
NO3: < 0.2
Cu: < 0.5 mg/L
<I hope so... should be zip, zero, nada>
*>>> 0.5 is the lowers the OceanClear test can show, water tested totally clear
so it should be 0.0.... never added copper to the tank
*
>Ah, good<
Alk: 3.5 mEq/L ( 175 ppm CaCO3 )
tank conditions are usually stable, I perform monthly 25% changes and rarely
check water for anything more the spg and pH unless there are visible issues.
I have had a banded cat shark long ago (~6years), when I was still in Israel,
unfortunately at the time I was totally unaware of the sharks sensitivity to
electrical currents and I guess that caused it to get really unwell and
eventually die :( it exhibited symptoms of *sporadic* twitching and laying on
its back on the bottom of the tank... Israeli electricity runs 220VAC and not
110VAC, which may have increased the problem even more...
<May be...>
After that I figured I should not try again, I have been diving since age 15 and
have seen other sharks in nature, I feel these beautiful animals should not be
captured for display by those who are incapable of caring for them, I certainly
was not.
<We are in agreement>
That said, last week when visiting the fish store I saw he had a newly hatched
banded cat shark and he mentioned the egg was there for 4 weeks now and no one
got it.. I was hesitating for a while because I feel my tank is much more
suitable than the store and the animal will die there eventually... Eventually I
decided to get the shark
<Not to go in the 100 detailed above I hope>
*>>> as I mentioned above ( or didn't ) it was kept in the store in a much
smaller tank with no sand and who knows what filtration, I think even the 100
gal small tank I can offer will be a better state until I can setup a system
that can support the animal or find someone who has it...
*
and with it all that I could think I need;
- I got the grounding probe which I so needed last time! (and good that I did,
before installing I checked the water against ground - 35VAC!! )
<Mmm, where is this stray voltage coming from? I would systematically unplug all
items... check their polarity, assure that they are all wired through a GFCI...
before running the tank another day>
*>>> I disconnected all power supplies, each contributes several voltages with
the 2 power heads and sump MagDrive being the highest contributors...*
>Do look into at least a plug in, extension cord type GFCI... Please read here:
http://www.wetwebmedia.com/gfcimarines.htm<
- I got *fresh* squid and shrimp but have not yet made feeding attempt - the
animal hatched 3 days ago, I figured ill give it till end of week to
acclimate...
- after reading your FAQ I will be ordering the supplement tablets you use.
<Mazuri likely>
*>>> yes*
I am aware of the fact this tank is way to*o*
<too>
small for this shark,
<So... what are you going to do?>
I have little rock arranged in a center island form so at this size it can still
*circle* it on the sand and have several caves to go under. Me and my wife are
planning to buy a house this year and I am planning to install an in-wall
300-400gallon aquarium, which should be more than sufficient. if this does not
happen and the shark gets too big to start getting abrasions by rock I will have
to donate it to the NY aquarium or anywhere else it can be cared for...
<... will likely be too late... all too common circular "logic">
*>>> I will gladly remove most of the rock that exists today if that's what u
meant by "circular", otherwise I did not understand the comment... why will it
not be a good idea to either work on a bigger system or relocate the animal
where it can grow?
*
>Sorry for the lack of clarity, communication... I mean that this animal will
likely perish first... the statement that "when" "then"... is what I am
referring to as circular... brings folks, the situation back to the beginning...
of no livestock<
so, as to my questions:
1. I have never medicated my tank at any circumstance, I feel if a fish gets
ick, lack of stress and good environment is the best I can do, if it does not
survive I feel bad but I do not want copper traces or any other thing that can
hit my corals ( mushrooms only really ) to be in the tank. I have recently got
some red slime growing in my tank and was wondering if the ultra life red slime
remover is a reef safe as claimed
<No...>
and more important shark safe and if I can safely use it to remove the red
slime.
<No... and what happened to your laissez-faire attitude re ich/disease above? I
would investigate causes and fix them...>
the seller
*>>> my no medicine attitude stays strong, this product was claimed to not work
like "normal medicine" which I the reason I posted this question BEFORE
considering it... I will read the below articles, thanks for the points...
*
argued it is antibiotics mostly and should not harm any reef animals but I am
not convinced.
<... Please read both:
http://www.wetwebmedia.com/maralgcidefaqs.htm and:
http://www.wetwebmedia.com/bluegralgae.htm
and the linked files above... The chemical trtmt. is very likely to result in
the loss of all livestock>
2. I have not been testing my tank as extensively as yesterday unless something
shows signs of trouble, should I be keeping more close tabs at readings with
this animal?
<Oh yes>
*>>> will indeed!!*
3. how do you know if its a boy or girl? :)
<Posted... the presence/absence of claspers...>
4. how often to feed? last time I was offering every day, the shark would eat
but not everyday, but always by morning it was gone somewhere... wondering if
this is not too much?
<posted and posted and...>
5. any additions/changes to the *filtration* systems I should be thinking of?
any special concerns when planning the *filtration* system for the new planned
tank?
mainly I wanted to know about the red slime remover... tanks for all the helpful
info!!
regards,
Etay

*>>> I am not sure if the last comment was put in anger or not, I have never
visited your site before and have no intention of "abusing your trust" whatever
that means, I am well aware of searches but I must say that it took me several
hours just to find this email address and even then I only found it by mistake
since all the actual email addresses in the site (BobFenner@wetwebmedia.com and
others) don't work and I was struggling to send this email... I intent to read
as much as I can but wanted to get immediate answers to some of what I thought
are important questions... I read 3 Banded Cat Shark FAQ pages before I sent
this email and I had at least 20 more questions I did not need to ask because I
already found answers....
>I see... we have recently changed ISPs and the personal addresses with the WWM
suffix no longer are active... I am trying to fix all on the site... to not
direct folks to email addresses that don't exist... but is taking time<
not sure what you mean by "much to take in" but your response makes it sound
like I am immature, and that I don't know what I'm doing and while I am not a
marine biologist I do everything I can to care for my animals and never
underspend what needs to be spent to get the correct system and equipments... as
you mentioned yourself, "I try to design my system around the animal and not
around the budget" and while I cannot put a 400 gallon tank in the apartment
I
rent right now, I fully intend to do so when I get a house, regardless of
weather I had this shark or not, it was in the plans for a while, I just got a
reason to do it faster... I am hoping it will be able to be kept in the
100Gallon tank in the next 4-5 months, if you don't think that's the case I will
start looking for good places for it now... will still get the 400Gal anyways
though...
>Mmm... my comments are value neutral. I am neither angry nor consider you
immature or otherwise... Just have enough understanding re this field to urge
your diligence in reading, caring for this shark...<
all in all I really like your site and you guys offer a lot of good info but I
feel like I was just "washed" for attempting to do a good thing.. I think the
chances of it surviving in store are much smaller and felt really bad for it..
*regards,
Etay
<Mmm... Shalom, BobF>
Re: Banded Cat Shark - Some
Questions – 08/31/07
Bob,
<Etay>
Again, I must thank you for all the information and help. I started reading the
article you directed me to, about BGA. It is fascinating and will take me a
while to go over. I will definitely continue to visit WWM, until now I did not
know any site that offered so much advice and information.
I'll take some time to go over more of the posted info before I bug u guys with
too many questions...
<No worries>
thanks for the help!
e
<A pleasure to share. BobF>
