Are there any Cichlids that would work in a 6 gallon Eclipse bowfront tank? I currently have a 55 gallon community (my first tank) but I'm really interested in Cichlids. My current space is VERY limited, so I would like to do a very small tank. Is there a Cichlid that would do well on it's own in a tank of this size? Or even one small enough for a mated pair, 2 ladies and a gent, etc?
