背棘 (總數) : 9; 背的軟條 (總數) : 12; 臀棘: 3; 臀鰭軟條: 12; 脊椎骨: 25. Body depth 2.75-3.2 in SL. A broad band of small scales extending from below eye to slightly below corner of mouth; 2 or 3 scales dorsoanteriorly on opercle. First and second dorsal spines flexible, about twice length of third spine, slightly longer than longest dorsal soft ray, and not separated from remainder of fin; space between 2nd and 3rd dorsal spines about 1.5 times greater than space between 3rd and 4th spines; membrane between 2nd and 3rd dorsal spines incised to about 1/3 length of 3rd dorsal spine. A small black spot a scale row below 8th lateral line scale (above tip of pectoral fin). Both sexes with a row of orange dots along lateral line and scattered dots below, posteriorly on body; females with a large roundish pink patch dorsally on abdomen containing oblique orange lines on scale edges, ending dorsally in orange spots; males with black lines variously under edges of 2nd to 6th lateral-line scales, sometimes extending to row above or below, and no pink patch on abdomen (Ref. 39775).
Body shape (shape guide): fusiform / normal.
體高 2.75-3.2 分之一標準體長。 延伸的一個小鱗片的寬地帶些微地在嘴角之下從眼睛下方到; 2 或 3 鱗片背面前面地在鰓蓋上。 第一個與第二背鰭棘柔韌有彈性的, 大約兩倍於第三根棘的長度，略長於長的背部軟鰭條, 而不是與其餘的鰭分開; 間隔的空間第二與第三個背棘大約 1.5 倍大於間隔的空間第三與第 4根棘; 在第二與第三個背棘之間的薄膜對第三個背棘的大約 1/3 長度呈鋸齒狀的。 在第 8個側線鱗片 (上方胸鰭頂端) 之下的一種小的黑色斑點鱗片列. 雌雄均有一列橘色的點沿著側線與分散的點在下面, 在身體後面; 雌性具有一個大的圓粉紅的小區塊在橘色的斑點中背面在鱗片邊緣上包含斜的橘色線的腹部，終止背面上; 在第二到第 6個側線鱗片的邊緣下面各種不同地雄性有黑色的線, 有時延伸至列上方或在下面, 與在腹部上的沒有粉紅的小區塊.(參考文獻 39775)
