They are aggressive, so they will eat whatever is there if they are hungry. I believe one guy is having issue with that on this message board. He is thinking of getting rid of it to a big Aquarium.

As for my opinion, I agree with Huma-Huma! If the fish looks healthy and is happy looking than why do we yell so much at someone? I personally want to have a few Cat Sharks some day in my store, just to have something to talk about with people.

Sharks create a large bio load, so if your filtration is up to it, it can be done. Lots of work keeping a big animal like these when they get full grown. And you are not likely to find rehousing him to be easy. Most public aquariums won't touch fish coming from hobbyists, for obvious reasons.

As to an earlier comment about stocking, the fish are very poor communicators. They only way you can tell if you are stocked properly or improperly is the behavior and feeding habits of the fish. Their overall,health will indicate if you are doing fine or have a problem.

so would you agree its safe to say that we as hobbyists usually form imaginary limits to stocking and tend to fall victim to the belief that theres a set,proven way to determine stock level?

You have to start some where. When making recommendations, I tend to be conservative as a result of running what I thought of as responsible fish shops. I have been dealing with aquarium headaches since I was 18 and that was a long time ago. Stocking isn't a science, but there are some lessons to be learned. My dad use to say there was nothing to be learned from the second kick from a mule. If 80% of those you talk with have had disasters created by the same poor stocking decisions, you tend to lean in that direction. There are always folks that have had a different experience, which you fairly note, but 80% means there is a good chance you won't win the gamble.

Back to the cat shark, when they are little they eat a lot of food because they grow fast, which is where the filtration comes in. I would guess feeding them properly is a big part of successfully raising one. We have a local LFS that has a shark tank, a pool that's about 1000 gallons. They seem a bit cramped to me, but they are healthy.

I house five sharks in a 7ft x 7ft x 3ft tank. Bio load is ridiculous. My filtration is a 300 gallon sump with. Carbon and phosphate reactor. Two 1000 gallon skimmers. Uv filter. Enough matrix to filter the ocean. I change 120 gallons of water a week and my nitrates stay around 20-30 and have been as high as 80. Lot of work. I go through a bag of large shrimp every 10 days and a bag of scallops every three weeks. One bag of whiting every two months. They are all around 2ft to 2.5 ft. Two white spotted bamboo. One brown banded bamboo. One coral catshark. One banded houndshark.

Mind sharing a pic with us? Not a lot of people can say they have a shark tank

I have since had an issue with my starfish eating all of the mushroom corals in the tank and the sharks toppling most of the rock causing me to rearrange. And just when everything was perfect I added a powder blue tang that infected my tank with Brooklynella. I lost everything except the wrasse who is a nightmare and the two squirrelfish. The sharks and eel are were all fine but I lost everything else. Also there were more fish in the tank than what is pictured. I lost about 5-6k worth of fish.
