Predominantly piscivorous by nature, although gut analyses of wild specimens also showed it to also consume various aquatic invertebrates. The presence of terrestrial plant matter in some fish was probably via the stomach contents of their prey.

Can be aggressive, especially towards conspecifics. may be kept with other large cichlids or as a species only setup. Likely to eat any fish small enough to be considered food - and they have big mouths!
