Growth and behavior
Juvenile to adult
Juvenile
As a juvenile it feels safer in a group and usually uses the midwater area with coordinated movement. An insufficient group can increase stress and erratic behavior.
Shift
The transition to adulthood usually brings more stable behavior when group size, space and parameters are suitable.
Adult
As an adult it keeps a strong social pattern and is more stable in adequate groups. In balanced communities it usually occupies the midwater area without causing major conflict.
