Blue Dolphin Catfish?

[kewpiefishypewpie]

Hello all,

My LFS has had this catfish for sale forever. Labeled a blue dolphin catfish? Really cool active fish. What is it?

It's a potentially parasitic Cetopsis coecutiens catfish.

http://www.seriouslyfish.com/species/cetopsis-coecutiens/ says Best kept alone, as not only will it eat smaller tankmates, it will often bite chunks out of larger fish as well. In nature, it has been seen ripping pieces of flesh from much bigger fish than itself. Some success has been had with keeping it in groups, as it seems less likely to regard conspecifics as a source of food.

https://www.planetcatfish.com/common/species.php?species_id=339 says 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 because they are young or well fed. It will however always eat smaller fish and is an accomplished hunter.

Ever keep one? Max size?
