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 | 產卵場 | 卵 | 孕卵數 | 仔魚
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。
