It is almost impossible to keep this fish in the aquarium at home because he gets to big.  It is is a large predator that will eat smaller tank mates. This species is very aggressive towards similar species and should be kept single. The aquarium should be planted on the sides and background.  In the middle there should be a lot of free swimming space,  The aquarium should be well covered because they are good jumpers. 

You should give them large live food.  Occasionally they accept dry food.

Breeding has succeeded.  After spawning the male takes the eggs in the mouth and there they are incubated.  The young fishes stay there during 50-60 days.  When they leave the mouth they are already 8-10 cm (3-4").
