Provide ample swimming space with rockwork for shelter. Maintain excellent water quality—sensitive to poor conditions. Feed multiple small meals daily (2–3 times or more). Diet should include mysis shrimp, brine shrimp, copepods, and high-quality marine foods. Strong filtration and oxygenation are essential due to their active nature. Behaviour & Temperament Peaceful and highly social schooling fish. Best kept in groups (harems)—one male with multiple females. Males may show mild dominance displays but rarely cause harm.
