I'm waiting to see the price of a coal grunter (New Guinea fish) in a week or so, but if it's too costly, I may go with a young cichlid for a lone fish/55 gallon. I know all the reasons to get the grunter, but I wondered if anyone would like to vouch for a cichlid. So far, my cichlid choices are a grammode, or a cuban. Any others that would make good 55gallon pets?
