sa/ca cichlids are nice and have a little personality to them. I would get 1 firemouth, 1 port cichlid, keep your jewls, get a blood parrot or 2, maybe an ecoloti... not many options for a medium sized tank beacause most cichlids get pretty big... a 75+ gallon would be much better... Just shoot for a bunch of smaller one or 1 or 2 larger ones...
