Greenish brown above, often with dark blotches and bright milky-white spots above pectoral fins; underside cherry red (males) or light orange (females) with white spots; fins with dark bands (Ref. 4698).
Found on rocky bottoms with sand or mud, or among seaweeds (Ref. 4698). Benthic (Ref. 58426). Feeds on fishes, large crustaceans, occasionally polychaetes and amphipods (Ref. 4698). During the spawning season, the male's underside becomes deep red with white spots.
Eggs are deposited in a clutch on the bottom and defended by the male. Larvae hatch after about 5 weeks.
