Maturity: Lm ? range ? - ? cm
Max length : 15.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 26340)
背棘 (總數) : 12; 背的軟條 (總數) : 14 - 17; 臀棘: 2; 臀鰭軟條: 13 - 15. Juveniles are reddish orange above, with small bright blue spots on forehead and dark spots at upper pectoral fin base, dorsal fin, and caudal peduncle; colors disappear as fish grows larger (Ref. 26938). Adults dark gray to blackish with vertical black lines on body; a black spot, sometimes diffuse, at upper base of pectoral fins which are pale; other fins dark (Ref. 13442).
稚魚是橘紅色上方, 在上面的胸鰭基底，背鰭與尾柄的前額與深色的斑點上有小的淡藍色斑點; 當魚生長比較大的時候，顏色消失。 (參考文獻 26938) 成魚深灰色到黑色的在身體上有垂直的黑色線; 一個黑色的斑點, 有時擴散的, 在上面的胸鰭基底鰭，那是灰白的; 其他的鰭深色的.(參考文獻 13442)
Adults inhabit rocky shores exposed to wave action. Often in tide pools. Feed primarily on algae and detritus. Territorial and pugnacious. Generally common (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Taken incidentally in traps and small-meshed beach nets (Ref. 5217).
棲息於被暴露於波浪活動的岩岸。 常見於潮池。 主要吃藻類與碎屑。 具有領域性與好鬥的。 普通地常見.(參考文獻 9710) 在魚籠與小網目的海灘網中附帶地捕獲了。 (參考文獻 5217)
