The Coral Hawkfish most often rests in or under the corals to ambush its prey, mainly crustaceans and small fish. In this species, territorial males form a harem of females. Reproduction occurs in the water column, with eggs and larvae developing in ocean currents and becoming part of the zooplankton.

The African clown wrasse, or Coris gaimard, is a solitary fish that changes color throughout its life, transitioning from orange with black and white eye spots in juveniles to a multicolored pattern in adults. Females turn into males, recognizable by the large green lines on their head. This species mainly feeds on mollusks, crabs, and hermit crabs and primarily resides in reefs.

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.

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.
