背棘 (總數) : 12; 背的軟條 (總數) : 15 - 16; 臀棘: 2; 臀鰭軟條: 13. Anal fin long and pointed, reaching well beyond base of tail (Ref. 26938). Adults dark gray-brown, the edges of the scales blackish; a wash of yellowish often present dorsally on head, nape, and on back below spinous portion of dorsal fin; a small black spot at upper base of pectoral fins; juveniles bright yellow with two bright blue lines dorsally on head, extending to beneath middle of dorsal fin where they break into spots; a large blue-edged black spot basally on dorsal fin centered on last spine (Ref. 13442).
臀鰭長而尖的, 延伸到尾部的基底後面.(參考文獻 26938) 成魚深灰色-褐色, 鱗片的邊緣黑色的; 洗淡黃色的時常存在的在頭部，後頸背面上, 與背面在背鰭的刺狀部分之下; 在上面的胸鰭基底鰭的一個小的黑色斑點; 稚魚鮮黃色的有兩個淡藍色線在被延伸至背鰭的在下面中央的頭部背面上在那裡它們斷掉變成斑點; 一個大的邊緣藍色的黑色斑點基部地在背鰭上在最後的硬棘上集中了。 (參考文獻 13442)
Adults inhabit coral and rocky reefs of sheltered lagoons and inshore areas. Territorial and pugnacious (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).
