Way of life
The fish lives mainly on seagrass meadows and rocks overgrown with algae in shallow water up to a maximum depth of 30 meters, although it is also found in tidal pools . It feeds mainly on small fish, crustaceans and other invertebrates.
The spawning season falls on the seabed from February to May. The approximately 1.5 to 1.8 millimeters large, yellowish eggs are laid in clumps between algae and in crevices, with the male guarding the eggs until they hatch and thus actively caring for the brood . After about 6 weeks, the 5 to 6 millimeter long larvae hatch. The larvae are pelagic , the fish become sexually mature after about 2 years.
