I have considered getting a black or blue Bullhead catfish for my 125 Gal. tank, but their reputation for violence seems to be at par with Leatherface. I have read that they only get about 16", but that they cannot live with other fish, including other Bullheads. Is this true? I know a Channel Cat would get along fine with my other fish, but C.C's get way too big for a 125 tank. I would think that if a C.C. is a compatable tankmate, a Bullhead(much smaller) should be OK as well. Does anyone keep these cats?
