Growth and behavior
Juvenile to adult
Juvenile
Juveniles may look more tolerant, but they already show exploratory and opportunistic behavior. Plan the community around adult size, not only the young stage.
Shift
Territorial behavior may become more evident with sexual maturity or during breeding periods.
Adult
As an adult it strongly shapes the community through size, mouth capacity and feeding behavior. It should only be kept with robust, proportionate species and enough space.

Opportunistic
Profile: predatory species, with low bioload and primary use of the bottom. It can adapt to calm communities, although it usually behaves better with compatible companions. It may show opportunistic predation toward fry or very small animals. Provide hiding places, visual barriers and enough room to prevent constant pressure.
