Ctenochaetus striatus, elegantly named the "striated surgeonfish", is found in the tropical waters of the Indo-Pacific, particularly in the lagoons of La Réunion and Mauritius. In Tahiti, during the full moon, this fish displays a natural spectacle: large schools form, and after a brief moment of stillness, each individual breaks away to release eggs or sperm.

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.

This butterflyfish is easily recognized by its elongated snout, which is useful for capturing aquatic microorganisms among corals. It also uses it to peck at the feet of echinoderms, the pedicellariae of sea urchins, and the tentacles of marine worms.

The checkerboard wrasse inhabits the slopes and sandy expanses of lagoons and coral reefs. Its diet primarily consists of prey with tough shells. It can be observed at depths of up to around 30 meters

This eel-like fish digs a tunnel in the sand leaving only the front of it body out. The garden eels live in a colony of several hundred individuals, where ocean currents carry the plankton on which they feed. At the slightest sign of danger, garden eels entirely hide in its shelter.

The bluestreak cleaner wrasse feeds exclusively by parasitically cleaning larger fish and turtles. In the reefs, it coordinates a cleaning station, typically near branching corals. Particularly active at the beginning of the day, these small cleaner wrasses clean the gills and mouths of many fish species.

This large unicorn fish is a common inhabitant of lagoons and reefs with strong currents. Primarily diurnal, it feeds on brown algae like sargassum. It can be encountered in small groups or solitary.
