Description

The Panamic sergeant major is a damselfish of the family Pomacentridae from the eastern Pacific. The species has a deep, silvery-yellow body with five dark vertical bars, the so-called sergeant stripes, and reaches about 20 cm. It inhabits rocky and coral reefs, often in large aggregations, and feeds by day on plankton in the water column, supplemented with benthic invertebrates and algae. In the breeding season a pair forms and the male guards the demersal eggs that adhere to the substrate. Juveniles sometimes pick parasites from other fishes.
