hey my name is weronika and im new to the site.. i currently have a 35 gallon hex freshwater aquarium containing 2 red parrots, 2 golden severum, and a small pleco. im kinda new to this stuff but ive read bout fish tanks for a yr. be4 actually getting one. i originally wanted a brackish water tank but i must of set it up like 3 times wit no fish and it failed be4 i could ever get any fish. so recently i went 2 the lfs and got a fish they called the blue shark. online i found it is actually known as a blue whale catfish and tends to be agressive unlike the fish store told me. but im willing to get a bigger tank prob a 75-100 gallon tank. but what would i keep with it? and it hasn't eaten much wut could i feed it? :)
 
there are a lot of fish they call blue shark, a picture would help, as some grow to 4 feet long and some are small parasitic catfish, and some are just mellow little fellows. welcome
 
the actual name for it is cetopsis coecutiens.. and i havent found much info on it on the web.. im not sure exactly how to put up a picture on here. and theres a video on youtube of one exactly lik mine exept bigger. i type in blue whale catfish on youtube and its the second video. the thing that gets me about the video is how is the morray eel in there if its freshwater not salt or brackish? imma try to put my pic up if it works thanx
 
I'll upload them to this post so it's easier for others to see.

What have you tried feeding it so far? They are meat eaters so I would try prawns, cockles, mussels, whitebait.... foods like that. They have very poor eye sight, so they do need to sniff the food out, therefore it is handy to keep water flow to a minimum during feeding time. They can be veracious eaters once they get the taste and yes they can be aggressive (but more on the eating side than bullying, i.e. feeding frenzy). Tanks mates should be chosen wisely, for their tank mate perspective of being eaten, and from the blue whale cats perspective of not getting picked on as it cannot see well at all. All in all, a bit hit and miss with tank mates.
 
thanx.. ive tried feeding him frozen blood worms and carnivore sinking pellets he hasnt touched the blood worms even though im happy cause my other fish love them.. but he ate 3 of the carnivore pellets last night.. the thing is i feel its a hit or miss with his eating because today when i fed him the pellets he wouldnt touch it. yesterday he only ate them as they were sinking.. once they hit the bottom of the tank he doesnt attempt to reach them anymore.. do u think a bigger tank would help him search the bottom for food?

agreed.
theyre not exactly aggressive.
just blind.
so they go into a feeding frenzy and will take bites out of other fish.
 
hi and welcome to the site , as the guys said this fish is near blind and survives in the wild by taking chunks out of other fish. it is a pretty hard fish to house for someone who is still pretty new to the game . tank size will not help matters but personally i would be tempted to take that fish back to the store from credit or swap for another fish.

if you decide to keep here is some info
it should get to around 10-12" ,

feeding :Will accept frozen foods and readily adapts to all good sized live foods. Chopped mussels and live earthworms are favourites. Should not be weaned onto feeder fish but attempts to wean onto tablet food (especially shrimp based tablets) should be made from a young age. Be careful not to overfeed as this fish is an opportunistic feeder and will gorge itself given the chance.

Furniture A sparse, dimly lit tank is required. Provide only minimal cover for the fish to hide in during the day. The provision of a dim actinic light will allow you to observe the fish on its nocturnal prowlings where it is an impressive midwater fish and needs room to roam.
Compatibility Not a fish to be trusted with others. Its natural adult behaviour is to bite lumps out of larger deep river channel fish such as the scaleless Pimelodids. Younger fish in the aquarium do not seem so dangerous, perhaps becuase they are young or well fed. It will however always eat smaller fish and is an accomplished hunter.
Suggested Tankmates It is believed these are a shoaling fish, but no data is available on keeping them as such in aquaria. Perhaps armoured catfish are the best bet, but ensure all fishes are well fed.
