背棘 (總數) : 12; 背的軟條 (總數) : 13 - 16; 臀棘: 2; 臀鰭軟條: 12 - 14. Caudal fin slightly forked, with rounded lobes. Dark blue or brown above, yellow below, without obvious narrow vertical lines. Dark spot near back of dorsal fin well above its base becomes smaller in larger fish (Ref. 26938).
尾鰭些微地分岔, 有圓的葉。 深藍色或上方褐色的, 黃色的在下面, 沒有明顯的狹窄垂直的線。 在背鰭的背面附近的深色的斑點在較大的魚中在相當上面距離它的基底變得比較小的.(參考文獻 26938)
Adults occur in seagrass beds, coral or rocky reefs and sandy areas. Also found around mangrove shores and sponge beds; less common on flourishing coral reefs (Ref. 26938). They remain within 50 cm from the substrate. Adults feed on algae, polychaetes, amphipods, foraminiferans and gastropods while juveniles feed on harpacticoid copepods, nemerteans and polychaetes (Ref. 9626). 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). Caught incidentally in traps and small-meshed beach nets (Ref. 5217).
出現於海草床，珊瑚礁或岩礁與沙地。 也紅樹林海岸與海綿床的周圍發現; 較不普遍在繁茂的珊瑚礁上.(參考文獻 26938) 在 50個公分從底部裡面保持。 成魚吃藻類, 多毛類動物，片腳類動物, 有孔蟲與腹足動物而稚魚吃哲水蚤，紐蟲與多毛類動物.(參考文獻 9626) 附隨地在魚籠與小網目的海灘網中捕捉了。 (參考文獻 5217)
