oscars... intelligent?
Lol.
It doesn't take much to equate a face with food. Or learn that doing an action means food. I mean they arent dumb. But they aren't smart lol. and yes I HAVE kept an oscar from 2 inches to 12 inches. If you mean do they interact with owners as an oscar does, yes most will. It depends on the individual fish. Cichlids, and other fish, are mostly Instinct. I also have yet to see a fish with at least some ability to learn.
