Females light greenish gray, becoming pinkish ventrally, with diffuse orange-red stripe from behind eye to base of caudal fin; a broad white area over abdomen, the lower part with vertical lines of red; there may be faint red bars on the body. Large adult males lose the distinctive red, white and black markings; they develop a vertically elongate blue spot on each body scale; a yellow head with near-vertical pale blue bands, and a large dark spot in axil of pectoral fins (Ref. 13442).
雌性淡的灰綠色, 腹地變成略帶桃色, 有擴散的橘紅色的斑紋從眼睛後面到尾鰭基底; 在腹部上的一個寬的白色區域, 下面的有些有紅色的垂直線; 在那裡在身體上可能是模糊的紅色橫帶。 大的雄性成魚失去特殊的紅色，白色與黑色的斑紋; 他們在每個身體鱗片上發育一個細長垂直的藍色斑點; 黃色在胸鰭的葉腋中頭部有接近垂直的藍灰色條紋 , 與一個大的深色斑點。 (參考文獻 13442)
Most common in open sandy areas. Feeds on small sand-dwelling invertebrates. Dives head first into the sand when frightened. Generally common (Ref. 9710). Generally of no interest to fisheries because of its small average size (Ref. 5217).
