I just got a new 46 gallon tank and want to set up a community tank. I want a few bigger fish, but not huge fish, just 5 inches long or so. I was thinking of some cichlids, anyone have any suggestions? I'm also thinking of getting clown loaches, kuhli loaches, a plecostomus that stays small, some barbs and maybe a school of small tetras. Do cichlids like to live in groups, or are they fine living solo?
