This fish lives near diadem-urchins. At the slightest danger, it takes refuge between the long spines of sea urchins. The male guards the eggs in the mouth until they hatch. It is threatened in the wild because of fishing for the aquarium trade. This species breeds in captivity.

The large pectoral fins of this fish serve as a fish net to capture prey. Its color (alternating dark and light bands) indicate to predators that it is poisonous: there are poison glands in the skin covering its spines. It can cause serious or fatal accidents.

This moray is narrower than most other species. Over time, the male becomes a female (protandrous hermaphroditism). This sex change is accompanied by a color change. This moray adapts easily to life in the aquarium.

During the day, it lives in schools and often "grazes" Posidonia leaves (underwater flowering plant). It also eats small animals that live hanging on the leaves. Juveniles live in very shallow waters. It flesh, soft and bland, is not appreciated.

It swims very badly and lives on the bottom where it is camouflaged among underwater vegetation. It is hunting from a hide and, like all the scorpion fishes, it is venomous. Very sought after for its flesh, it is easily captured with a harpoon or a net.

It often lives below 30 meters depth. In the spring, it goes close to the surface to spawn in the sea grass. Its spines are venomous. The sting is very painful, but rarely fatal. It is one of the essential ingredients of bouillabaisse.

It breeds easily in captivity. During mating, which can last between 30 and 45 minutes, the male forms a loop around the body of the female. Its flesh is edible, but it liver is toxic. Its reproductive behavior has been studied at the University of Liège.

It is especially active at dusk. During the day, it stays on the bottom. It can close it eyes with a sort of eyelids. Its flesh is edible, but it liver is toxic! Its eggs can be incubated and hatched in an aquarium.

It is very aggressive towards fishes from its species, except during the breeding season: In the spring, at nightfall, a pair forms and performs a complex courtship. It is a synchronous hermaphrodite: male and female at the same time. Very curious, it often approach divers.

The eye of this fish is masked by a black band that disrupts the visual perception of it body by predators. It has venomous spines on the dorsal and pectoral fins. It is easy to maintain in captivity but they need hiding places for shelter.

During breeding, the bream groups enter lagoons and estuaries to mate. Sought after since the Antiquity for the quality of its meat: the Romans fattened bream in tanks. Its intensive pisciculture has developed since the 80s.

By day, these fish form a small group and remain free from branched corals. At night, the group dislocates and specimens go down near the bottom for food. During the incubation period, the eggs are kept in the mouth of the male. The latter fasts until they hatch.

During the day it feeds on plankton near the surface. It descends to the bottom before dark to capture small invertebrates. The male is more colorful than the female. It is a protogynous hermaphrodite species: females become males. Its flesh is not appreciated.

It differs from other species of wrasses because of the elongated shape of it head. Those who live in the Posidonia meadows (underwater flowering plants) are entirely green. The male builds a nest of seaweed and gravel where it distributes the eggs until they hatch.

The sailfin snapper frequents sandy bottoms in the immediate vicinity of coral reefs. This usually solitary fish preys on other fish, crustaceans, and various mollusk species. It is a tropical fish occasionally targeted by fishermen.

The skin of this species secretes a toxic mucus for predators and parasites. This fish is territorial and fights involving males are common. To lay eggs, both partners embrace and rise to the surface to release their reproductive cells that will be mixed by sea currents.

The sixbar wrasse frequents shallow lagoons and offshore coral reefs. It lives in small, scattered groups and spends its days hunting small fish and foraminifera, tiny single-celled organisms. Like other wrasses, this fish changes color throughout its growth.

The moon wrasse inhabits the coral reefs of the Indo-Pacific. This species is sometimes referred to as the moon wrasse due to the shape and yellow color of their caudal fin. This wrasse primarily feeds on small invertebrates residing in the rocks and fish eggs.
