herbier - Discover fishes living in these biotopes

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.

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.

Its shape and color helps it hide perfectly among the underwater plants. There are similarities in the way it reproduces compared to seahorses. The male has no pocket, but it carries egg rows glued to a ventral furrow.

The twotone tang, like its counterparts, possesses scalpels at the base of the caudal fin. In times of danger, it can extend two small blades for protection against predators. Adults of these fish typically live in groups of around twenty individuals. They gather in large schools to spawn during the breeding season. They are exclusively herbivorous and graze on algae in coral-rich areas.
