In nature they share habitat with Vieja harwegii, and breidhori, and live bearers preying on the young Vieja. and live bearer fry.
I acquired a half dozen juvies from an American Cichlid Assn auction, and housed them with mollies in a 6 ft tank.
As they grew, they ate all the mollies, and then proceeded to kill each other off.
I was left with a pair, that spawned 3 times over the next couple years. Great fish to keep but very shy, so do a lot of hiding except when guarding fry.
In a 6 ft tank, they objected to the addition of any other cichlid, by quickly killing it.
In a 300+ gallon tank, they might accept others.
