Demoiselle - List of fishes

The caribbean sergeant major is a tropical fish associated with coral reefs and rocky tropical areas of the western Atlantic Ocean. This small schooling fish has a morphologically very close cousin throughout the Indo-Pacific region: A. sexfasciatus.

This damselfish lives in shallow waters of the Pacific and Indian Oceans. It feeds on algae and small invertebrates, and is recognized by its 5 black vertical stripes and the fluorescent yellow band under its dorsal fin.

It owes its name of pomfrets to its coloration reminiscent of a chestnut. In spring, males defend a nesting area and ventilate the eggs until they hatch. Juveniles are electric blue and live in small groups.

The blue-green Chromis is a fish that lives in large schools above dense coral areas. At the slightest alarm, this swift fish takes refuge in the colonies of branching corals. The Blue-green Chromis is common throughout the Indo-Pacific region.

The goldtail damselfish is a tropical fish native to the Indian Ocean and the southern tropical zone of the Pacific Ocean. Like many of its kind, this species lives in small aggregations among the branches of "stag horn" corals.

The whitetail Dascyllus resides in the tropical waters of the Indo-Pacific region and the Red Sea. This white reef fish striped with three black bands is often found in large groups above massive colonies of staghorn corals. It feeds on zooplankton, benthic invertebrates, and algae. During the breeding season, males choose the nest and perform a dance just above it as a courtship display. The female is then invited and escorted to the nest where spawning takes place.

The common name of this species refers to the patterns observed in young individuals. Adults typically live among the arms of branching corals, while juveniles more often reside among the tentacles of anemones. These fish are omnivores with a carnivorous tendency.
