I guess it came in with some tetras at the lfs and was there for about 6 months with another one. The other died and he took this one. They were feeding it brine and some type of flake. They said it hadn't grown much, if at all. (wonder why? They are feeding it flake) Thanks for the ID guys! I'll let him know.
He has it in his community tank which I told him last night wasn't a good idea, I didn't know what it was but I could tell it looked like it could eat some stuff.
