Growth and behavior

Juvenile to adult

Juvenile
As a juvenile it is usually more flexible and less dominant than an adult. Even so, it benefits from cover, stable parameters and tank mates that do not compete intensely in the bottom.
Shift
The transition to adulthood usually brings more stable behavior when group size, space and parameters are suitable.
Adult
As an adult it behaves as a territorial cichlid or fish and needs space, tank mates and activity level to be well balanced. Its impact increases when bioload or competition is high.
