ok already have a green terror tank and a 6ft piranha tank, and need stock ideas for a 55g in my living room. nothing in it right now, but i dont know what to get. im contemplating possibly a cichlid tank or maybe even trying saltwater. just looking for something that looks good and i prefer a few larger fish than a bunch of little fish. colorful is good, and my girlfriend hates "creepy fish" any ideas would be great THANKS!
