Red devils,dovii, and flowerhorns can hold their own, with lots of personality. PBass get huge and beautiful. Catfish rarely come out and get large. Pacu get very large, but are kind of a dumb fish, love to hit the sides of the tank.
i feel the dovii and red devil are the better choices. lol. im not sure about the flower horn. and catfish are boring and obviously pacu are dumb.haha. how big do dovii and red devil get?
I was reading on wikipedia,which usually has very good info on cichlids, that a Midas for some strange reason usually get along with jaguars.Give the Midas a try though,they may become the best of pals ever.
