May enter semi-enclosed sea areas; forms schools over rocky bottoms (Ref. 11230). Nocturnal species (Ref. 7300). Breeding pairs are found from July to September in Japan. Mouth brooding is done by the male (Ref. 240). Monogamous and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884).
