Best Shark for 8'x2.5'x2.5'
Setup? 12/31/10 Horn Shark and Smooth Hound Compatibility... no reading, mixing tropicals with coldwater sharks that need non-hobbyist settings 8/20/08 Good Afternoon, fellow fish lovers! <Good morrow to you> My boyfriend and I have recently upgraded my shark tank from a 180 to a 240 inset through a wall in my dining room, it has a central overflow and whirlpool current to promote circular swimming. Sadly, in the process we lost our second leopard shark, <Dismal... why haven't you read my posts, articles ahead of writing us here?> the first committing suicide one night. <Inappropriate species for such a small, squarish, likely non-chilled setting> We came across a deal for a 17" California Horn Shark and have a couple of questions. First, how compatible is a Horn Shark with a 16" grey Smooth hound shark? <Mmm, very> Secondly, I have a 5.5" Koran Angel, a 6.5" Vlamingi Tang, a 5" Yellow-bellied Hippo Tang and a 4" hog fish in there as well. <... not compatible with these tropicals. Again, what are you doing writing here? You should be reading, ahead of such purchases> I am very worried about the first three fish, especially the Koran Angel (he was an anniversary present a few years ago) and the Hippo Tang (have had her for almost 5 years). How strong of a possibility is it that they could become shark food? <Not very hard> My Hippo Tang likes to lay in the rocks a lot and I am worried that one day she will choose the wrong cave. We will be setting up a shelf to give the horn shark a "home" to retreat to during the day, any tips on helping her find and settle in that area? <Let's just stop here. Is this Heterodontus francisci? Read here: http://wetwebmedia.com/portjacksons.htm and the linked files above.> Finally, she has been at this store for over two months and I have been told that she is eating well. <Leave this animal where it is> It will take me two hours to get her to my house from the shop and am a little worried about the acclimation process (the shop provides almost coffin size boxes for ease of transportation). Do you have any tips on the least stressful way to acclimate her and getting her to eat? How long does it typically take to get a shark like that to eat? I know with my smooth hound it was a couple days, one of my leopards a day and the second took 4 to 5 days ( I was stressing). I love my fish like they are my children <... Not per my definition. IF you love something, you endeavour to know what is good for that/those things... and provide them. You have done neither> and I don't want to do anything to hurt them. As you can tell my boyfriend is the aquarium expert in this relationship, I am no novice but I am nowhere near his expertise. Thank you so much for your time and consideration in this matter, you have no idea what it means to me. Sincerely, Katie S. Samarin <Read Katie... Know, act, this is love. Bob Fenner> 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> Shark senses, systems 1/17/06 Hi I have a Banded Bamboo Cat Shark, is it alright to put a titanium heater in the tank with it? Thanks <Mmm, if necessary, yes... though it is far better to remote heating, and all other metal containing gear outside of the main system... for danger to it from the sharks movement and more importantly protecting the shark from the ill-effects of electro-magnetic and ferrous presence (there is some iron inside the heater...). Seek info. on the Ampullae of Lorenzini here. Bob Fenner> Sharks and Corals 7/19/06 Hello. <Hi there> I have a 300 gallon shark tank with 2 young banded bamboo shark in it that hatched at my home. <Neat> I have a very large cave structure that is cemented together in the center of the tank that they sleep in and prowl around. <Good layout> The rest of the tank is open water. I was wondering since my rock work is so stable and I can't even topple it over if that I could keep some SPS corals on the top of the cave close to the surface to dress the tank up a bit. <Mmm, maybe...> I would choose corals that don't sting of course. <Not really much of an issue...> Would this be a problem? <Likely will have problems with water quality for the SPS (need high biomineral, alkalinity content), perhaps easily knocked off the rock at night...> In the wild they live around the stuff so I figured it would be ok. Any input would be much appreciated. Thanks. Justin. <Worth trying. Bob Fenner> Coral Cat Shark Information - 3/4/05 - del Paulio Hi WWM
Crew, I have a few questions regarding coral cat sharks.
<Well, much of the care for these animals has been answered in our
sharks area on our website.> I am planning on buying one in
the next week or two, but I want to set my questions straight before I
do anything... <I don't recommend keeping sharks in
aquaria.> ... (so I do not wind up hurting or insufficiently
equipping the shark). <Don't buy one is the best thing you
can do for a shark> First off, I would like to thank you and
your site for all of the info you have already given me.
<thanks for being part of it all, Matt> So my first
question is, if I have a 75 gallon tank, how long could I safely hold a
coral cat shark? <Well about a year but look at the
information here: http://www.wetwebmedia.com/marine/fishes/index.htm
it is the first group and look through our FAQs. Do some
research.> I am planning on buying a 180+ gallon tank as soon
as needed. <I recommend a larger tank that is wide and long.
the height is secondary> What is the minimum size tank I would
need to hold a full grown CCS? <Look here: http://www.wetwebmedia.com/marine/fishes/index.htm
It has been answered many times before> Secondly, what would
you recommend to feed it? Eel and Shark, Lava rock 3/11/05 Hello, Can you tell me if Lava Rock would be ok in a tank with a Snowflake eel and bamboo shark? <likely safe... but always some risk/extra algae with terrestrial rocks><<Mmm, too sharp... little help with biofiltration, water chemistry. RMF>> My tank is 65"X25"X25" My filtration has around 100 lb of live rock in my sump 1 canister filter 1 protein skimmer. I can't seem to find anything about Lava rock in fish only salt systems. Can you please help me. Thank you <go to our index page at www.wetwebmedia.com and simply type in "lava rock" in the Google search tool. Enjoy the journey. Anthony> Shark Tank Substrate Hi Bob, I very much appreciate your site and the wealth of information you offer, and thank you for all your time and advice. <No problem.. it's what we're here for!> I currently have an existing 40 gallon setup with silica sand that would serve as a temporary quarters for a banded cat shark until the larger tank (125 gallons) is fully cycled and ready to accept such a huge load. A larger tank will be procured/converted as the need will soon arise. I have read over the information on your site and did not see anything pertaining specifically to using silica sand vs. aragonite/crushed coral for shark keeping. I do realize the benefit of the buffering capacity of the latter, but this should not be a concern as the well water I am on has a high PH. I keep a freshwater hystrix ray in a 200 gallon setup using natural sand, and the ray is doing very well. I have stayed out of the way of silica sand for the ray due to the potential to scratch the belly of the ray and allow for infections. Is this advised for a shark as well? Thanks for your time and insight! Mike <Mike as you know this shark will require a 200 plus gallon tank in around a year or so. You might want to try and get the 200+ instead of the 125 so there is less hassle! Sharks need the finest sand possible so shoot for natural sand instead of crushed coral/silica. You'll be thankful when the shark doesn't get scratched up. BTW how big is this shark? 40 gallons even for a baby is way too small. You need to but the baby in a bigger tank ASAP. Hope this helps! Phil> Titanium Heaters with Sharks Hello, Sorry for bothering you all so much. In my attempts to provide the best habitat for my bamboo shark, I may have inadvertently made an error. I have been sparing no expense by purchasing top quality equipment and am using two titanium heaters with remote LCD displays. I am worried that the titanium housings may upset the shark. I prefer this heater because it appears more durable and will not shatter like its glass counterparts. On the other hand, if there is a chance of it upsetting my sharks, please let me know and its gone. Thank you very much. Mike <Good question... I would mount these heaters out of the main system, perhaps in a sump, just in case. Bob Fenner> Shark Tank Substrate He's a freshly hatched shark... about 6". The 40 gallon has a 36" x 18" bottom. I don't want to decommission one of my 200 gallon tanks (1 x Silver Arowana/Stingray tank, 1 x African Cichlid tank) until I know the shark is doing well enough, hence the interim 125 gallon tank. I will be very mindful of the shark's size and bio-load on the aquarium, and will convert the 125 to a full out reef when the shark is moved. Just to confirm what you mean by natural sand... not aragonite, or any other commercial sand. Sand such as you'd find at a beach, right? Thanks again! Mike <Sorry for not being clearer. Sugar sized sand is best. About the same size as beach sand would be best. Good luck to you and your shark!! Phil>
Leopard shark habitat Hey Mr. Fenner! I really enjoy the information you have to give about all species of sharks. <Wait till you see Scott Michael's new book on the group...> I have a 125 gallon (about 6X2X2 feet) set-up with nothing but live rock and sand. I would like to add a Leopard shark. I live in the basement of a house and the water temp. stays at 65 degrees year round. Would this set-up be alright for a leopard shark? <Only temporarily for a small specimen... and then not very "humane"... A Triakis will be very unhappy in such a size, shape tank, being able to only turn around in one direction in a short while, for a short while... Study this species from afar, visit it in Public Aquariums, perhaps the wild... maybe try a Bamboo or Epaulette Shark or even small Catshark species..., or even hatch one from an egg instead. Bob Fenner> Brownbanded Bamboo Shark I currently have a newly hatched specimen (not eating yet but it has been less than a week) as well as an egg case waiting to hatch. Is a 125 large enough if I only keep one and trade in the other at the LFS? <For maybe six months to a year or so yes> Should I upgrade tank size? <Absolutely> What size would you recommend if I kept both? <At least a "standard" shape 240, 8'X2'X2'... better, bigger> Will the other inhabitants cause trouble in the future? <Perhaps... Large Angels, Triggers, Puffers et al. might bite your sharks... Basses, other eager eaters consume all their foods...> Currently I have minimal decor (I have recently removed some LR to make room for the shark(s) to move freely about) but there are caves and ledges made from LR to make the pup feel secure. <Sounds good> There are also some hard and soft corals. <Keep these up and away from the bottom... and your eyes on them... would leave some "outside light on" for the shark to navigate at night times> The tank was 2 years old before introducing the egg(s). The other inhabitants are a snowflake moray, a purple tang, a bicolor angel, a flame angel, an ocellaris clown, and a Foxface. All of these except for the clown and the flame have been in the tank since it cycled. The clown and flame were added about 2 months ago. I use an oversize skimmer as well as mechanical filtration. The water parameters are SG 1.024, pH 8.3, cal 450ppm, ammo 0, nitrite 0, nitrate 20ppm, temp 80. Sorry for all the questions but I want to ensure I provide the correct environment for the sharks now and thru maturity. Thank you. Steve <Thank you for being concerned enough to seek others opinions. Do keep reading, perhaps writing about your shark experiences for others benefit. A very popular area of interest for hobby magazines, the Net... Bob Fenner> Shark Tank Substrate Question Dr. Bob, <No doctorate puhlease> Been thinking about changing strategies regarding how I setup my sand bed to best facilitate detritus consumption and general water quality support for a 500 gallon tank whose primary occupant is a Bonnethead shark. <A few ways to go here... as you likely know> Currently, sand is sugar-sized aragonite, from 1² - 2² in depth. General maintenance is provided be two 3² goatfish, 5 sand-sifting stars, 2 small queen conchs, a couple of Mexican turbo snails, about 25 Nassarius (sp?) <Nassarius> snails, a few bristle worms and assorted tiny stuff. I was thinking about increasing sand bed depth and trying to propagate critters to create a live sand bed. Stuff like Mysis shrimp, Gammarus shrimp, miniature brittle stars, more bristle worms, orange spaghetti worms and micro stars. <Sounds neat> Also, I¹d greatly increase the number of Nassarius (or however you spell it) snails. Of course, if I wanted to propagate these critters in sufficient numbers, I¹d probably have to eliminate the goatfish and reduce the number of sand-sifting stars. What do you think? Which way would you go? Am I O.K. as is, or would the extra expense of creating and seeding a more fully ³live² sand bed pay off? J.D. Hill <I wouldn't spend any money on seeding this substrate... the live rock will do this completely. Bob Fenner> Re: Shark Tank Substrate Question But would you: 1) Leave the sand depth as is or go deeper? <As is> 2) Pull out some of the rampaging goatfish and sand-sifting stars temporarily to let the critters get better established, or leave everything alone? <Leave as is> Also, are you familiar with a reddish brown shrimp like creature that grows to a length of about 3/8"? Any guesses? <A reddish-brown shrimp-like creature, small. Bob Fenner> J.D. Hill Re: Shark Tank Substrate Question Not to be confused with the dreaded reddish-brown shrimp-like extra small, I hope?? <You're cracking me up this AM... Can't quite make out what it is from where I'm keying here... but likely a crustacean to be eaten soon. Bob Fenner> J.D. Hill Re: Shark Tank Substrate Question .and any more responses like this and I WILL be deleting the "Dr." honorific! You're cracking me up!! <Oh, oh... we're starting to use the same expressions... Soon be wearing similar clothes. Hope you don't mind tees and shorts. Bob F> J.D. Help for the big tank guy <Heterodontus> Hello again Bob, I have written you in the past about my large systems, 800 gallon angelfish, 500 gallon reef. Now that my house has finally finished all of the cleanup and we're fully settled my tanks finally are too. <Must be a relief!> I sold the contents of my 800 gallon angelfish, most of which funded my 400 gallon office show tank filled with Fathead Anthias, about 22 and Green Chromis about 30 or so, really a spectacular tank especially on a reef setting. <Neat... and all the Sunburst/Fatheads get along?> The Boston Aquarium was generous enough to accept my 16 inch emperor. In return I was hooked up with a deal from a neighboring fish farmer with a 1 1/2 foot horn shark. I put him in the 800 in a cold water setting with very little rock work except for a large cave at one end, mostly large beds of kelp-like grasses to provide a san Francisco bay type setting. The shark seems to be thriving and what I thought would be the biggest eye sore is non existent, him laying on the bottom like in the those undersized nurse shark tanks. Obviously being a Horn Shark he still does this but he is a very active swimmer. He eats well and enjoys the occasional urchin which gets very interesting. <Hmm, yes... I have a pic of a Heterodontus francisci swimming about in Scott Michael's new Shark and Ray book... am quite familiar with this species> What kind of things should I mix into his diet to ensure a long life? <Most anything will do... the name "hetero" and "don't" point up the fact that these small temperate and tropical sharks can/do eat hard-bodied organisms... like the urchins you mentioned, clams, crustaceans... as well as fish...> He thrives in the cold water but how cold is too cold? <Below 50 F. or so. But I would keep mine at nearer 70 F. so you don't go broke chilling water, or blind from squinting through condensation, and your shark will move about more at this elevated temperature.> Its been a pleasure to do this project the right way, the fish has lots of swimming room and it really looks great. The 500 is taking on full life, it turns the corner of my living room into the hall and is longer then wider, more so than usual. I have added a lot of water flow on the branched off section that's in the hall (about 100 gallons of room there) to accommodate my final additions, 3 Jewel Tangs, (Acanthurus guttatus), thanks to the Marine Center. <Wow, have rarely seen this species kept... just not offered in the trade... congratulations> Its kinda like a surge zone with only the hardiest of my corals. Its a pretty cool effect. The Semilarvatus B'flys are growing nicely, all three are now about 6 inches. The Sohal has also maxed out at about 9 inches now. Most of the little fish have been removed except for the occasional cleaner wrasse, I think I still have two, and a group of Catalina Gobies that have really done better than expected in their own little territory near the far glass against a rock wall. What other requirements do the Jewel tangs have? <About the same as the Naso lituratus... lots of room, rock, greenery to eat, water movement> They seem to be healthy after a month of quarantine (I was extra cautious be it I never used e-fish purchasing before. They only feed really well on Nori right now though. What else do they eat? <Mostly green, brown, red algae, but will eventually take most all foods> The Majestic Angel was also removed after he suddenly went violent on my corals. Any reason for this? <Just happens at times> Thanks for all the help, you've contributed a good deal to helping my tanks get to the way they are at this point, nice and steady. Kev <Outstanding. Glad to have helped. Bob Fenner> Re: Shark Question What is the best type of substrate for Coral Catsharks or Brownbanded Bamboos in your opinion? <Please read over the cartilaginous fishes sections on WetWebMedia.com Bob Fenner>
