I have a 40g square tank, and I'm looking for some fish to put in it. I really like Keyhole Cichlids, and Festivum. I can get large Keyholes and small Festivums. I think they're both about the same in aggressiveness, and getting them sized the way I want to do it should be ok. I have other tanks if the Festivum get to be too mean.
Any comments?
