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 Malabar grouper is a fish native to the Indo-Pacific region. Adults can reach considerable sizes, with recorded catches of individuals over 150 cm and 50 kg. Sought after for the quality of its flesh, this species is captured through various methods such as line fishing, trawling, longlining, traps, and even harpooning. In Hong Kong, it is sold as an ornamental fish. The species has nearly disappeared from several historical regions and is currently heavily overexploited in the waters of the Andaman Islands.

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 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.

The name 'unicornfish' refers to the protrusions found in adult individuals. These unicornfish inhabit the tropical waters of the Indian and Pacific Oceans. Throughout their growth, these fish continuously change colors and patterns. They usually live in small groups, but large schools can form in areas with strong ocean currents.

Young orangespine unicornfish live near rocky reefs, in the company of other surgeonfish. As adults, these fish find their food, leafy brown algae, in coral or rocky areas. They usually live in small groups.

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.

Naso vlamingii, more commonly known as the bignose unicornfish, is a surgeonfish found in much of the Indo-Pacific. It has a bump above its mouth from which a blue stripe runs to the base of its eyes. It has the ability to make this stripe appear or disappear.

Easily recognizable by its shape and blue color, this triggerfish naturally lives in groups in the turbulent waters near coral reefs. During the breeding season, males and females pair up to build a nest. They fiercely defend this small territory against other fish species and, more broadly, against any intrusion, even human.

The yellow boxfish is recognizable by its characteristic trapezoidal shape and its round mouth protruding like a beak. Its two large round eyes are prominent on the top of its head. Adults typically display a bright yellow color, covered with scattered black spots. However, there are variations in color such as ochre and blue, sometimes with white spots or black-ringed white spots, especially in the Red Sea. Juveniles are blue to greenish, always with the same pattern.

The palette surgeonfish sports a pair of venomous, erectable scalpel spines at the base of its tail, used for self-defense against predators. It primarily dwells in small groups within coastal reefs. Its electric blue color inspired the character of Dory in "Finding Nemo" and "Finding Dory".
