I am getting a 75 gallon aquarium on monday with a red shoulder severum, geophagus, Firemouth, and possibly a Pumpkinseed once well established. Though, I am not sure if the catfish that I want to get would be compatible with each other and the other fish. I am putting my striped Raphael catfish in from my 30 gallon so it is a definite as well as my sailfin pleco which is going to my friend when it gets to large, but was wondering if there is ANY possible way that I could get a bullhead catfish (Either brown or yellow) and it would get along with my other fish long term. Again, if there is any way I could get the bullhead, I would be willing to change any fish except the Raphael cat and the pleco.
