I like a lot of Central American species, but I find South America to be far, far more appealing in terms of fish diversity. I also like my biome specific aquariums, even though I never ultimately did a biome specific aquarium.
I do find myself drawn to them, save I can't seem to keep them for more than a few years. They also are not terribly aggressive, so other fish I get often outbully them. If only I could have more than one aquarium... oh well.Geophagus own my heart! Only centrals I’ve had were Texas and convicts but I’ve kept many different South Americans, Centrals are great but I’d have to go with south’s just because of Geos.
