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.

This fish is well known in our ponds. The reproduction in this species occurs from May to June, the females lay up to 200,000 eggs on vegetation near the banks. This fish can hybridize with many other species that breed at the same time as it (Roach, Bremen, Bleak ...).

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.

The black seabream is a prized species in western fisheries. It lives alone or in large groups near seagrass beds and rocky bottoms, seeking small invertebrates such as crustaceans or mollusks.

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.

During breeding season, its color becomes brighter and it builds a large nest with plant debris. It attracts the attention of females by performing a characteristic swimming. It will mate with several of them and it will protect and ventilate the eggs until they hatch.
