When you say “Community Fish” are you referring to non-cichlid tropical fish? Like Tetras, Mollies, etc? Or do you mean any fish that can be peacefully kept in groups?
Back in the 80s around Detroit the Term “Community Fish” meant little tropical non-cichlids… I don’t hear the term used the same these days though…
PS - Aquarium guy… I’m going to have to start smoking pot again to try to see if I can make sense of your signature… lol
