通常在第二背鳍鳍的 11个不分段的鳍条。 胸鳍鳍条通常 19. 前背的中线在后部地通常有比那些小的 13-16个圆形的鳞片，前面的鳞片。 在侧面上的鳞片与那些在尾梗上者大小相同。 腹面总是以非常大的圆形鳞片, 大约那在尾梗上与那些大小相同。 尾鳍有黑色或者暗色的马蹄形的条纹接近边缘，中间的鳍条黑色或暗色的.(参考文献 37578)
Adults inhabit fast-flowing sections of clear rainforest streams over rocky bottoms (Ref. 44894). Hatching and larval stage occur at sea, postlarval stage to adult in freshwater (Ref. 4343, 79840). Commercial in Reunion, where they are caught during the few days when they return from sea to enter the rivers (Doug Fenner, pers. comm., 2002, Ref. 79840). Smallest gravid female reported 5.03 cm SL (Ref. 37578).

Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Females when ready to spawn wriggles under a loosely set stone. The eggs are spread into a flat mass as the fish holds fast to the under surface of a stone. The eggs are fastened to the stones by the gelatinous threads that cover them (Ref. 110258). The male ejects his milt on the mass of eggs (Ref. 110258).
Spawning occurs in freshwater afterwhich eggs and larvae are washed down by the river current into the sea and goes back up the river after a month or so (Ref. 110258). The embryo development occurs in freshwater and the larvae should migrate to saltwater a few days following hatching. The larvae are carried by current to the sea where they grow up to the juvenile stage ("bichique"). At this stage the alevins get to the rivers and start going upstream during the new moon. They can go up to waterfalls higher than 10 meters with the help of their sucker-disc, that they can colonize waters up to 800m altitude (Ref. 48660).印度-太平洋: 東非到玻利尼西亞。
