Banded Cat Shark... sys. 8/8/07 I am looking into getting a banded cat shark. I would like to know everything there is to know about raising them and everything else. Also I need to know where to actually get one at. Can you help me out with this? >>>Greetings, While I don't have time to type "everything" for you, I can tell you that you need at LEAST a 180 gallon tank, and very little rock work. They are active during the evening hours. Cheers Jim<<< Shark Tank 8/8/07 Hello
everyone at Wet Web, I hope you all have been well! I have been doing a
lot of thinking lately about setting up an aggressive tank for my home.
A fish only with live rock set up. The tank size I have considered is
74"x36"x27" that's (LxWxH) My fiancé is
very interested in having a small shark in the tank, I know this limits
the variety and number of fishes I can stock in this tank considerably.
I have had my mind on Epaulette sharks. With this shark in the aquarium
mentioned above (311) gallons with a really built up wet dry filter
system, over sized skimmer, water flow no lower than 5,500 gallons per
hour in the display, live rock, and live sand would it be a good idea
long term to keep it with the following fish? 1 Blonde Naso Tang 5
Yellow Tangs 12 Bimaculatus anthias (1 Male 11 Females) or perhaps one
or two Heniochus acuminatus? (Rock work would be built up to the
surface of the water with plenty of places for the tangs, and anthias
to hide and sleep.) 1 Harlequin Tuskfish Would the Anthias be a
definite problem in this scenario to you? Do you think this tank would
be very over stocked? If I was to have to cut anything from the list
the Anthias would be my first pick. I would love to have the shark but
I really want some other fish to reside with it. I think the list
mentioned above would be beautiful together but I know that beauty and
compatibility are two completely different things. After seeing what I
am looking for if this list would not work, do you have any fish /
shark stocking suggestions for me? I am looking for a fairly laid back
shark species and bright, active fish to reside with it. Are there any
cleaner species you can think of that might do well with these animals?
Thank you so much for your time and expertise, Brian Crenshaw
>>>Greetings Brain, Jim here. I'm a bit confused as to
your "aggressive tank" reference. Are you under the
impression that any of the fish on your list are aggressive? You have a
pretty mellow tank there. You need a large tank for one of these
sharks, even the smaller species as they need swimming room. They are
quite active at night, and rock work needs to be kept to a minimum,
certainly not stacked to the surface. Don't be fooled by their
sedentary nature during the day. A shark tank is a different tank, and
you need to be prepared for this before you go and get one. While not
nearly the same thing as setting up a tank for a cruising species, you
still need to consider their needs in this department. They need space.
The stocking rate seems OK...maybe consider 3 Yellow Tangs instead of 5
to keep things down a bit. Anthias SHOULD be OK, but a small anthias
and an adult shark..... Cheers Jim<<< Saltwater Pond, for sharks - 06/27/07 As I have said before awesome site!!!! I have been reading about everything I could find about this subject. Hope this does not turn out to be a huge email. But I am planning on in the next year or two to add on a 24 x 24 room to my house. In the process I got the idea of possibly building a cement pond and use the epoxy they use for the plywood tanks to seal it. <Mmm, do look into strengthening the joints... perhaps fiberglass cloth and resin...> I want to put a couple Smoothhounds or dogfish in there nothing else. What would be the best size for this pond? <The bigger the better... at least three times the overall likely maximum size of species you intend to keep...> I know I want to max for the fish which ethically would be the ocean. But also know I have to do somewhat of a hex/oval part without 45 degree angles. I originally was thinking 96x96x24. <Way too small> But with chilling, water changes, and humidity I am going to go unfortunately minimum. Is 72x72x24 too small of a space for a couple dogs? <Arrrr, woof woof! Yes> I would be happy with one!!!! Am I wrong in thinking that the colder water, the humidity would not be as bad as my 240 fish only or my 95 reef setup? <Yes> I might have more questions but maybe in another email if you do not mind. <Not at all> But I guess my main question am I CRAZY in this venture???? <Not> I have year or so of planning and design maybe more. Just I guess is it possible with the information I gave you. I guess the main points are the pond inside with how I am constructing it and humidity issue and the huge chiller killing me in bills. Will not be light expect for lights above room so cut down on heat and Tunzes for movement. Thanks for you time!!!!! Mace <A neat project to consider, plan around... keep gathering data! Bob Fenner> Interested in shark...again -- 06/07/07 Hey guys, I have an extra tank that I never really set up... I got it about a year ago. The dimensions are 6 feet long by 3 feet wide and 14 inches tall. I was suppose to be a frag tank, but I don't really wanna do that anymore. I think I am just going to use my 90 for all my corals. Anyways, I have asked many people and they say a coral Catshark is suitable for life in this size tank. Do you agree? <For a period of time, yes... need a cover...> What are some tank mates I could have with it to? Oh yah I have all the equipment to, 75 gallon sump, skimmer, and lights. Which leads me to my next question...I was planning on putting corals in here so I have 3 175 watt halides, is this to much light for a shark? thanks, Chris <Please read here: http://www.wetwebmedia.com/marine/fishes/index.htm The tray, articles and FAQs files on Sharks in captivity. Bob Fenner> Magnesium effect on algae and bamboo shark - 05/26/07 Hello WWM crew, <Dave> Great site, the aquarist bible. I have 2 questions that I've been researching, that I was hoping you could help with. I have been having a problem with algae in my 100 gallon tank. Not sure if its hair algae or Bryopsis. I use RO/DI water doing water changes, 5 gallons a week. I also added a PhosBan reactor <For? You have measurable amounts of soluble phosphate? How much, from what source/s?> with Rio <I would "watch" this pump... and would NOT run with a shark present... due to ferrous/Ampullae of Lorenzini issue> 400 pushing it, about a month ago. Lighting consists of 2 150 watt halides and 4 55 watt pc's. Halides stay on for 10 hrs, pc's for 12hrs. Long story short, algae is taking over. I try not overfeed flakes or Mysis once a day, alternating between the Mysis and flake daily, for 8 fish. I was reading here:( http://www.reefcentral.com/forums/showthread.php?s=&threadid=1113109&perpage=25&pagenumber=1 ) that a good prevention for algae is to boost your magnesium. <Mmm, no... not unless the proportion is off...> Any thoughts on this? Also I have a month old bamboo cat shark that is temporarily in this tank until i move him into a 300 gallon pond designed especially for him. Will the magnesium boost effect him? Thank you for all your help. Thanks Dave <... keep reading. Bob Fenner> Getting Back Into the Game; Bamboo Shark Care -- 05/03/07 Dear Crew, <Hello Bill'¦> Thanks for the wonderful site you have put together. <You are welcome and thank you.> I've been reading all the FAQ's (its taken me several days- not a joke) and I just wanted to say a few things. <Be my guest.> I was surprised at the redundancy of a lot of questions. Do people not read FAQ's before they send in questions? <Sadly, no'¦> Wow- READ UP FIRST PEOPLE!! <Agreed.> Anyway, I had a few of my own.... <No problem.> In a couple of questions, Bob had recommended adding vitamin solutions to food offerings for sharks. Makes sense. He had also said to add Iodide supplements as well, but in a previous question, I think it was MikeD who had said not to do this, as it could prove fatal. Which is it? <Over dosing iodine is indeed something the aquarist should be aware of'¦though through a disciplined practice it should not be an issue. The occasional dosing is necessary (happens anyway with water changes)'¦it is also recommended that you soak the food in an iodine solution on occasion to prevent goiter.> I'm confused, is it only certain species or an age range that is the key factor? <See above; also if you want more detail I would look into Scott Michaels book; 'Sharks and Rays.'> Also, I know most sharks are nocturnal, <Most of the benthic species we keep in the 'average' aquaria; yes.> and therefore spend most of the day "sleeping." As I work late at night this is fine. My question is if I come home at maybe 11 to midnight, the shark should be active, but would prefer the tank lights to be off. So are there any lights that would allow me to watch him at night without interfering with his natural clock? <Low watt L.E.D. lighting or a red incandescent bulb.> Like "safe lights" used in photo darkrooms (deep red lights that wont exposed normal light sensitive photo paper)? Or possibly "black lights"? <No not black-lights. See above.> And should I just have my regular tank lights kick off at sunset-ish and just use the "spying" lights afterwards? <Yes use a normal lighting cycle; and then as you put it the 'spy' lights to view the animal later.> Anyway. I found you site while trying to research shark aquarium keeping and have been hooked ever since. When I was living at home with my parents, my step father (who probably knows more marine biology than most biologists) had a banded bamboo. We never really had a problem with him, not till he got big enough to try to eat a bird wrasse (my moms favorite) and a spiny puffer (the other favorite). I believe he was a good two to three foot at the time. Anyway, my mom made us get rid of him (he went to a trusted LFS who specialized in exotics). Ever since then, I've wanted to get another one. After being on my own for several years, I came across an aquarium setup (at a garage sale) that I couldn't pass up. I set it up with the idea of getting a banded bamboo once again. Though he might be the only thing in there besides "live in food" (e.g.. ghost shrimp, etc. ). <I would recommend a VERY large/oversized protein skimmer.> Which brings me to my last question, How can I encourage "natural" hunting behaviors? <In young specimens; ghost shrimp (like you mentioned above) and fiddler crabs. Having said that I'm not really a fan of live-foods. I prefer varied captive fair; mussels, scallops, squid, krill; etc. . Soaked in iodine now and then and vitamin supplements like Selcon.> What edibles can I keep in the tank for him to hunt, as enrichment (sorry, zoo term)? <See above.> Thanks for your time. I will reference your site for all my future questions. Keep up the great work. <Thanks.> Bill <Adam J.> Flow rate in Elasmobranch display; sump and
refugia 3/5/07 Hey crew, <Hello.> I'm setting up a
180 gallon (temporary) shark tank <Key word being temporary.> and
have a question regarding circulation. <Okay.. I have a 100 gallon
sump (Rubbermaid tank) which is filled with about 60-75 gallons of
water, and a mix of live rock and bio balls as media. I also
have a 55 gallon refugium and big skimmer(1500 gallon an hour) plumbed
in. I figured I would circulate the tank through the sump
about 5 x an hour, does that sound right? <Yes, slightly more
wouldn't be a problem but this is fine, provided there are other
water-movement devices adjoining the display.> I'll also have
powerheads going inside the tank for added water movement. <Mmm...as
clumsy and as sensitive as sharks can be I would prefer closed loop
manifold systems if you can cut it.> What do you feel is
right for the circulation through the refugium? <Depends, what is
the targeted livestock (assuming it's a species of macroalgae here)
in it.> I appreciate your advice. <Of course.> Thanks
Cat shark: feeding and soft water 1/17/06 Hi guys, <Tim> I have a newly hatched cat shark and had two questions that I couldn't answer myself on your site. First, knowing that you don't recommend silversides as a diet for them I was wondering if it was ok to feed striped killifish (a common salt water bait minnow). <These should be fine> Second, do you know how this fish will do in soft water? When I set up the tank the softener was bypassed and it was filled with regular dechlorinated tap water. The manufacturer of the softener recommends that you gradually introduce the fish to soft water and it will be ok. Just wondered if this would be ok for such a delicate fish. Thanks for any help you can offer. Tim Taylor <Mmm... most water softeners are "exchange" in principle... trading ions for "hardness" material... and being re-charged with salt/s... One can end up with a bit of sodium/chloride imbalance... but not really much of an issue in an otherwise properly set-up and maintained system... I would not go to extraordinary measures to avoid the softened water here... Just mix, store your synthetic and you'll be fine. Bob Fenner> Tank size for Blacktip reef shark 1/10/07 Just wondering how large of a tank an adult Blacktip would need (not just "thousands of gallons" but actual range like "3000-5000 gallons"). Thanks for the info! < Please, please read *all* of this info! http://www.wetwebmedia.com/blktipshkfaqs.htm http://www.wetwebmedia.com/blacktipshark.htm -Graham T.>
Shark / ray tank 12/1/06 After some
thinking, and reading (I purchased Scott Michael's book, Aquarium
Sharks and Rays.), I have made some changes to my plans for
a shark tank. I plan to keep a brown-banded bamboo shark,
and maybe a more active fish with it such as a goat fish, or a smaller
snapper. <Good choices> My filtration Will consist
of a 75-100 gallon sump. First the water will
enter a chamber with a skimmer rated for 350 gallons. then
the water will flow over a 5 gallon bucket full of bio balls. After
moving through the skimmer and bio-balls the water will be used in a
fluidized bed filter rated for 300 gallons. there will be
some baffles at the end before the return pump to calm the water, and
add a location to use chemical filtration. I will have some
foam between some of the devices, and before the bio-balls. <Will
need to be cleaned perhaps daily in time... and you should monitor
nitrates... these will become an issue with growth> I
also plan to move the heaters to the sump. <Good> The
pump I have chosen for the return will be a Mag Drive 24. The tank will
have 3 1.5" drains <Perhaps 2" ID through-puts here> in
the top back of the tank. I have not decided yet if I will just use 90
degree elbows with strainers or if I will build a full length surface
skimmer box in front of the drains. I will have one sump
return line on each side of the tank, with an output at the surface,
and on half way down the tank wall. <With a check valve arrangement
to prevent back-siphoning in the event/uality of pump power loss>
This will give me 4 water jets in the tank for water to return from,
leaving only the elbows/skimmer shelf, and the
two return lines. I have combined these new
ideas from various reading on your site, Scott's book, TCMA, and a
few other internet sites. I am trying to make sure I get
this planned correctly before I finish my setup. My goal is
to have a very healthy system. I am just not sure on the best method of
filtration to combine in the sump that will be best for a shark, as
opposed to a reef tank full of live rock, which is what I see most
plans for on the internet. I have heard simply filling with
sump with live rock is not enough for potential bio-load spikes in the
tank, which is why I was thinking of a large amount of bio-balls and a
fluidized bed filter combined. <You are wise here... you still want
to address the driving of nitrification somehow/where however> I
have also come to the conclusion that a large skimmer is very
important. Do you believe this setup will give me good
success with this shark? <Can... with testing, good maintenance>
also, I am sorry for the badly formatted first email, I hope this is a
bit easier to read/understand. Thank you for your time, Daniel
<I's not i's... Bob Fenner> Shark Question/s... sel., health, fdg., sys. 11/14/06 Hey Bob, I am located in Toronto, Canada and was browsing your website and was fascinated by all the useful information I found. For the past 1 and a half months I have been doing a lot of research on the Brown Banded Bamboo sharks. I have read and gone threw <through> multiple websites, joined multiple forums, and bought many books including Scott Michaels " Aquarium Sharks and Rays" which was very informative. I will be purchasing a 250-300 gallon aquarium soon which will be the home for 2 Brown Banded Bamboo sharks. It will be a flat back hexagon shape with the dimensions 84x24x10x64 with a 30" height. Do these dimensions sound good for Brown Banded Bamboo sharks? <For a short while, for small specimens> For feeding would you recommend live food? <No... fresh/or defrosted meaty foods> Or frozen food. Most people I have talked to recommended frozen would, on a feeding stick to ensure I give both an equal share. But some say its easier to get them acclimated with live food? <Unnecessary> Is this correct or no? As well when I first introduce them into the aquarium how do I go about acclimating them? <See WWM re... marine fishes period> When I purchase them they will either be in eggs still or newly hatched. Should I leave them in the bags and place those bags in the aquarium like most fish are acclimated. Or should I place them in bucket with the same water as in the aquarium and then half of the water from the bag they came in? <This latter> Please let me know as I want to offer these sharks the best living conditions I possible can, and want to make the transition from the store to my aquarium as stress free as possible. I look forward to hearing from you. Thanks, Brenden Hewko <Will need more room in time. Bob Fenner> Brown banded bamboo shark ... health/system 11/5/06 Hi I have a Brown Banded Bamboo shark. I've had it for about 1 year and hatched it myself. <Ahh, congratulations!> The nitrates in my tank have been about 40 - 80 ppm its whole life and are at 80 ppm now. <Yikes... too high> My shark has never had <apparent> problems before and has seemed happy and healthy. I have been trying to get my nitrates to zero but have never succeeded even after doing a full water change before the shark was born (that only brought it down to 20 ppm). I have plenty of live rock in my tank which is 30 gallons. <Way too small... one, if not the largest issue here> I know that is way too small for my shark (it is about 11 inches now) and I just purchased a 125 gallon tank and it will be up and running within 2 days. Tuesday I came home from my dad's house for the first time in 5 days and went up to check on my fish. My shark looked like it hasn't been fed in a while because it had red spots on its stomach. <A bad sign...> I fed it about 2 to 3 silver sides and it ate them right away the red spots disappeared in no more than 10 minutes. Later I asked my mom if she fed it while I was gone and she said she fed it the day before about the same amount I fed it. After reading about the red spots from questions asked by other people, I have decide to do a 1/2 tank water change. <Good move> I was wondering if I should do more or less next time. <Mmm... thought you were setting up a 125...> Also what should I do if the red spots come back? <Improve the environment, improve the health... "If you can dodge a wrench..."> What kind of test kit do you recommend (I'm starting to think my current test kit isn't accurate)? <Posted...> And what kind of vitamins would be best to make sure my shark stays healthy? Thank you Brendan <Also posted... Mazuri... see WWM re. Bob Fenner> Sharks in a 75 gallon aquarium? - Part sixty-five billion and twenty... 11/4/06 Hi! Chad here again. Just wanted to ask if there is any way possible to keep a Freycinet's Epaulette Shark in a 75 gallon tank. Dimensions: 48in L x 18in W x 24in H. <Chad, haven't we been down this road before? The majority of literature on the Hemiscyllium freycineti advises keeping it in a 180 gal. tank. I know you claim to have read Scott Michael's articles, but let me point you back in that direction for a refresher: Mr. Michael's writes "A juvenile epaulette shark can easily be kept in a smaller aquarium, even a tank as small as the standard 20-gallon long. But the aquarist must be prepared to provide larger quarters as they grow, and they can grow fast! Juveniles may grow as much as 29 cm (11.4 in.) in a years time. At maximum size, most bamboo or epaulette sharks could be comfortably housed in a 180-gallon tank. The Hemiscyllium spp. are all found in tropical seas and will thrive at water temperatures of 22 to 29 ºC (72 to 84 ºF). Remember, at lower water temperatures your shark will grow more slowly." Taken from: http://www.advancedaquarist.com/issues/june2004/fish.htm So, yes, initially this shark would be OK in your 75, but you *must* be prepared to upgrade to a 180, probably sooner rather than later. Additionally, it is worth noting that the IUCN Species Survival Commission has listed this particular species as "near threatened" - do think seriously about wanting to house this creature in potentially less than ideal conditions...> If not, is there ANY shark species that I could keep in this size tank? <In a 75 gallon tank? Let me be very clear: NO. I know that my boyfriend Chris, who also answers queries for WWM, has already given you this answer. Thanks in advance. <You obviously enjoy these magnificent creatures...why not take up studying them in books, at public aquariums, underwater as a SCUBA diver, etc...you don't have to "own" them to enjoy them... Thanks, Chad <You're welcome. On a final note, Chad, we don't mind answering queries - that's what we are here for, but if you do ask a question once (or even more than once, in some cases), please respect the response you've been given. Even if you don't agree with the answer itself, by all means, keep researching on your own, but don't keep asking the same folks here to change their answers, as that tends to make us crabby after time:-0 Take care, Jorie> Converting to a Catshark Tank - 10/26/06 Greetings WWM Crew! <<Hello John!>> A little background on my situation: I have a 120 gallon fledgling reef that I started about 4-5 months ago. It has 4-110 watt VHO bulbs(2-10k and 2-actinic), and two 250 watt 10k metal halides. And, my wife loves banded cat sharks. <<Uh-oh...gonna need a bigger tank. Halaelurus lineatus (Lined Catshark) grows to just over two-feet...and if what you really mean is Chiloscyllium punctatum (Brownbanded bambooshark...often mislabeled by retailers as "Catshark"), these grow to four-feet in length>> My question is this: I would like to convert the 120 into a temporary shark tank until I can upgrade to a 280 gallon tank, and use my 55 gallon aquarium as my new reef setup. <<Be aware the 280 is still only suitable for the smaller of the two species mentioned. And do try to get your shark as an egg case and hatch it out yourself>> Which of the current lights should I leave on the 120, and which should I move to the 55? <<The shark will do fine under the VHO fluorescents>> Also, what would you recommend as far as the amount of LR to use in the 120, and should I keep any plants or grass beds? <<A "stable" collection of rock at one end with some "hidey-holes", and an open patch of sand will be fine...I see no need for plants or grass>> Thank you very much in advance for taking time out to answer my question. <<You're very welcome>> You have bestowed an incredible amount of knowledge to the public and we all thank you! <<Kind words for a collective effort...>> Thanks for everything, John Tedesco Active Sharks for a 1250? -- 10/25/06 Greetings WWM crew.
<<Hello James>> I'm having a custom made shark tank
built for a client. The tank will be oval, 8' long,
6' wide, and 3.5' high. <<Neat!>> My client wants
an active swimming shark, so bamboos are out. <<Mmm, but therein
lies the problem. 'Active' sharks require much more
space/care than this tank can provide; not for a mature animal...and
your client shouldn't consider keeping anything that can't be
cared for long-term >> I've been looking into spiny dogfish,
smooth-hounds, and as of tonight Bonnetheads, but I have a few
questions that I haven't been able to find answers to yet.
<<Temperate to sub-tropical sharks, will probably require a
chilled system...and even the smallest will likely grow to about
4-feet>> Firstly, which shark do you think would have the best
long-term success in this tank, and what numbers (single, pair, three)?
<<Um, not what you want to hear but...two, maybe three Bamboo or
Coral Catsharks>> Lighting - I was thinking of three 150 watt
metal halide pendants. Do you think they would be a good
choice, or too bright? <<Should be fine if they can be raised as
bit (will provide nice 'glimmer lines') and rockscaping is such
the sharks can reach/rest in shadow if they wish>> On a setup
like this, are a UV sterilizer and ozonizer necessary components, or a
waste? <<Both can be of benefit if sized/utilized
properly>> Water flow - Being an oval tank, should I try to
create a circular current, or would sharks prefer a more reef
like/random water flow? <<I think a 'circular' current
would work well...especially if it can be periodically reduced/reversed
(six-hour durations)>> I was planning on using either 3600 or
2500 GPH pumps to create two closed-loop systems, and I can run them
through a wave maker if needed. <<Sounds good...do have a look at
'eductors' ( http://www.aquaticeco.com/index.cfm/fuseaction/listings.categories/ssid/460)
for multiplying/spreading flow>> The tank will be filtered with a
very large wet/dry filter and protein skimmer. <<Might I suggest
a large fluidized-bed filter in place of/in addition too the wet/dry as
these are able to react very quickly to shifting bio-loads associated
with these big, messy feeders>> Lastly, (for now) I've read
on here several times about adding vitamins to their food, and have
followed links you've given to where the answers are supposed to
be, but I have yet to be able to find what kind of vitamins they should
be given, or the amount. <<Mazuri "¢ Shark and Ray tabs

I have been doing research on the Speckled Epaulette and the Freycinet's Epaulette Sharks and have found that they reach a maximum length slightly smaller than the other choices of sharks that I have questioned (besides the Catsharks). What size tank would you recommend for these shark species and where could I buy them (if the right specimen for a tank of this capacity)? Many thanks, <Chad, I have no direct experience in this realm, but have a very high regard for Mr. Scott W.

Michael's book on Aquarium: Sharks and Rays and have found it quite informative. That is where I receive all of my knowledge on sharks , and also , I have found that this website is just as informative as the book! My question is what size aquarium could I comfortably contain one of the mentioned sharks. Thanks, Chad <Most reputable info. says *at least* 250 gal. Please also see here for more info: http://www.wetwebmedia.com/sharkslvgrm.htm Jorie> Shark Tank...Not To Be - 10/06/06 Hey Eric, Chad here again. <<Hey There Chad!>> Was emailing to tell you that I am now getting a 265 gallon aquarium and was wondering if I could still keep a Brownbanded Bamboo Shark in it and maybe a few fish also. <<Bummer dude...the 1200 gallon "oval" would have been so cool. I'm afraid I'm of the opinion the 265 will be ultimately too small/the wrong shape for this 40" creature. Best to turn your attentions to a new direction/a different species interest I think>> Thanks, Chad <<Regards, EricR>> Re: SHARK QUESTIONS!! Sys., Heterodontids 10/2/06 Ah yes. Thanks! I have another question though!! I have a powerhead on this system to add a little movement. Should i remove it? <Possibly> Also I have a titanium ground probe to remove stray voltage from my aquarium but before I added it on i tried it on a tank with no fish (the tank am cycling) and when i touched the water it sort or gave me a little feeling of electricity!! <What? I would have this water/system tested... Make sure all electrified gear goes through a GFCI. http://www.wetwebmedia.com/gfcimarines.htm> Is that supposed to happen or am i not supposed to be able to feel it? <Assuredly not... Deadly dangerous> I removed it immediately and haven't used it since then!! would this harm my shark or help it? <Harm> i don't want to add any voltage or electricity to my water for good reason and concern of my beautiful prized shark!! Also I have a friend who is interested in a Port Jackson! He has a very large tank and can house it!! What information or tips can you give me so I can correctly advise him? Thanks again!! <Please read here: http://www.wetwebmedia.com/portjacksons.htm and the linked files above. Bob Fenner> Need Help With Bamboo Shark - 09/26/06 I have a 60 gallon salt water aquarium. Up until 2 days ago the only thing in it was a clown fish around 2 and a half inches who lives in my sea anemone. <<Nothing wrong with keeping it this way...>> My tank is running great, I'm happy to have so much growth inside, mushroom corals, bubble algae, feather dusters, sponge corals and a few things that I'm unsure of the names thrive in my live rock. <<A great hobby, eh?>> Ok I'm sure you must hear this all the time, I have a friend who bought a banded bamboo shark (around 10 inches I would say) and she only has a 30 gallon tank. <<Uggghhhh! If the LFS where she bought the shark knew this........!!!>> Right away I said "why did you do that?" "it's going to die in there" well, she figured out about 2 days later that she didn't want it and came to me. <<...? Why not return it to the LFS?>> I told her no because I knew there wasn't enough room in my aquarium for a shark. <<Indeed>> But like she said it's better off in mine then hers until I can find someone else to take it <<Mmm...semantics...>> (I work in a pet store so I'm sure I can find a better home for him). <<Is there a suitable tank at the pet store to house this animal until then?>> I'm curious about their behavior, hopefully you can help. <<I shall try...but you will likely find more info with a keyword Google search re on our site/the NET>> I want to know that I'm doing what I can to keep it alive. He seems to want out, he goes to the top of the tank and looks like he's trying to find a way out. (it makes me really sad to watch it) Also it scratches on the rocks and sand. Is that normal? <<Under these circumstances, maybe...signs of a healthy animal/environment, no. There is something in this environment that is irritating this creature...could be water quality...could be stray voltage/magnetic field from a "leaking" powerhead or some other electronic device. Do read through our "shark system" FAQs for clues...you can start here (http://www.wetwebmedia.com/sharksystems.htm) and do also follow the linked files above>> There are no signs of ich. I watched it turn upside down and scratch its back in the sand. <<Not necessarily a "parasitic" reaction>> I'm no expert on behavior, do you think that is normal? <<Nope>> Also, how much food they need at one sitting? (Is feeding him every 2 days ok? and how much?) <<Offer a small amount of marine based meaty food daily (shrimp, squid, fish flesh), and do have a good read here (http://www.wetwebmedia.com/sharkfeedingfaqs.htm)>> For my last question, how well do they see? Some times it runs in to the rocks and glass of my tank. <<Mmm, environmental again...does this shark have anywhere to get away from the bright lights of a reef tank?>> Thanks so much, I only want to help <<Understood, but this animal needs a more suitable system...and soon. In the meantime, do avail yourself of the plethora of information on these amazing creatures posted on our site>> -Liz <<Regards, EricR>> Re: Need Help With Bamboo Shark - 09/28/06 Well, I work at PETCO; there isn't a tank large enough or really safe enough to hold him. <<Okay>> Also I'm worried about returning it to the store, because they will only resell it to another unsuspecting customer who will kill it. My friend said it was housed in an aquarium way smaller than my 60 gallon with around 10 other banded bamboo sharks. <<Mmm...>> It really is a bad idea for it to go back there. I'm going to turn off my power heads, and see if his behavior improves (I have 3 in my tank for the coral). Yes he can escape the light quite easily, and has dug several holes under my live rock to hide. <<Ah, good!>> I moved all the live rock to the center so that the shark could swim around. <<Excellent>> Thank you for your help, I'm going to visit a fish store tomorrow that I think may be a good choice for a permanent home for him. -Liz <<Good luck with your quest.
