Way of life
Spotted wrasses live in the area of coastal algae-covered rocks or seagrass meadows at depths of 2 to 20 meters, a maximum of 50 meters, where they occur singly or in pairs. The diurnal animals hide in crevices and hollows at night, they mainly feed on crustaceans and molluscs .
The breeding season extends from April to August. At this time, the males become territorial and build nests of plant material in shallow hollows on the sea floor. The females lay the yellow eggs, 1.1 millimeters in size, from which the fish larvae with a length of 4 millimeters hatch. These live pelagic and later move to the coasts, where they live in tide pools . The juveniles reach sexual maturity after about 2 years, the maximum age is about 18 years.
