Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm TL 雄鱼/尚未辨别雌雄; (Ref. 90102)
背棘 (总数): 10 - 11; 背的软条 (总数): 14-16. Has a tall dorsal fin and small tufts below the chin (Ref. 48636). Resembles P. thepassii and P. variabilis but usually has fewer total dorsal fin elements (Ref. 37816).
在下巴之下有一个高的背鳍与小的簇。 (参考文献 48636) 与 P. thepassii 与 P. variabilis 相似但是通常有较少的总背鳍要素.(参考文献 37816)
Adults occur solitary (Ref. 90102) usually over sandy areas of reef flats and shallow lagoons. Small juveniles were found below the upside-down jelly Cassiopea that moves over sandy substrates providing safe travel (Ref. 48636). Eggs are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Females nest in empty mollusk shells (Ref. 1602). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
出现于礁石平台与舄湖浅滩的沙地。 筑巢在空的软件动物外壳中。 小的稚鱼在上下颠倒的水母 Cassiopea 之下被发现在沙的底部上的移动而且提供了安全的旅行.(参考文献 48636) 卵生的.(参考文献 205) 筑巢在空的软件动物外壳中。 (参考文献 1602) 卵是底栖与聚集在一起的。 (参考文献 205)
