I have a 55 gallon aquarium with 5 fish: peppered cory catfish, plecostomus, gold gourami, red fire dwarf gourami and an opalene gourami. the tank is still young so I don't plan on adding new fish for a while but I was wondering if there are any cichlids that are peaceful enough to get along in my tank, specifically with the gouramis. I read that some people have had luck with rams and apistogrammas in a community but they could get aggressive when breeding. I suppose all this assumes that both species don't require different pH and hardness etc... Any ideas/advice would be greatly appreciated. This is my first post so I wasn't sure where to ask this question, whether in a gourami or cichlid sub forum so I felt the newbie forum would be best. If this was the wrong place to post then I have an excuse b/c I'm a n00b!
