Well, I've raised several Crenicichla Strigata( I think), and let me say that I look high and low for any and all types of Pike Cichlids. Nothing has been more enjoyable than to watch a Pike feast on feeders. I know it sounds sick, but come on...it's incredible. These fish have a ferocious appetite and tolerate NOTHING from other species. I don't care what kind of wild, crazy cichlid you have, a full grown Pike will win a tank war. OK, maybe the only competitor would be the African Fighting Fish or a Payara, but nothing else.
Actually, I'd like to know what other fish people think would be more dominant and ferocious that a full grown Pike?
