Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335).
More on author: Tanaka.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; non-migratory; depth range 3 - 30 m (Ref. 125611). Tropical
Western Pacific: restricted to Japan and Taiwan, with vagrants ranging southward to Malaysia.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 9.5 cm SL male/unsexed; (Ref. 125611)
Dorsal spines (total): 13 - 14; Dorsal soft rays (total): 11 - 12; Anal spines: 2; Anal soft rays: 9 - 10. This species is distinguished by the following set of characters: D XIII-XIV,11-12 (usually 12); A II,9-10 (usually 10); pectoral-fin rays 18-20 (usually 19); pelvic-fin rays I,5; caudal-fin rays principal 15, branched 13; procurrent spiniform caudal-fin rays 2; tubed lateral-line scales 16-19 (usually 18-19); gill rakers 7-11 + 18-23, total rakers 26-33 (usually 26-29) (Ref. 125611).
Adults inhabit lagoon and seaward coral and rocky reefs (Ref. 9710). Prefer habitat consisting of boulder substrates or mixed rock, rubble, and sand, at depths between about 3 and 30 m (Ref. 125611). Oviparous, distinct pairing during breeding; eggs demersal and adhere to the substrate, and males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699).
