Ok, I have a Red Devil and a Jack Dempsey they've been tank mates for about 2 months now, maybe less. Anyhow, my question is what other sorts of tank mate can they have I just want one more fish, if possible if it's not then that's ok. My next question is, is there any type of cichlid or "aggressive" type of fish that can live in a 10 gallon by itself or perhaps in a pair? Thanks in advance!
