Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Found in shallow rocky bottoms from 5m down to 30 meters (Ref. 37679). They are solitary dwellers and live around nests buried under stones (Ref. 37679).

Life cycle and mating behavior Maturities | Αναπαραγωγή | Spawnings | Egg(s) | Fecundities | Προνύμφες

Oviparous. Spawning takes place under nest stones (Ref. 37679). Egg masses are guarded by males (Ref. 37679). The male hovers around the female to initiate the courting phase, fully extending all his fins, opening his mouth, showing his gills, and slowly fanning his caudal fin. The body and fins of the male turn black, in contrast to the reddish orange margins of the dorsal and caudal fins. The female doesn't show any color change (Ref. 37679).
