Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.1 cm TL male/unsexed; (Ref. 9626)
Red to dusky red with a round black spot beneath rear of second dorsal fin and a broad blackish saddle-like bar on caudal peduncle.
Commonly found along sea walls and pilings, in harbors, and coral reefs. A nocturnal species, it remains hidden in cracks and crevices during the day (Ref. 9626). Reaches depths of more than 100 m (Ref. 9626). Males with eggs have been spotted in Bahamas in June and July (Ref. 26938). Most common cardinalfish in the aquarium trade.
