I have a 125g cichlid tank and a 30g breeder tank. I want to set up my 55g with tropical fish because im sick of all my tanks being cichlids. I want a tank with alot of small fish and caves. Im thinking a red tail shark, 3 cory cats, 12 neon tetras, 6 glow fish, and more. I want 100% peaceful. No fin nippers like tiger barbs, silver dollars, mollies. Any ideas?
