Body shape (shape guide): elongated.
Adults inhabit small, clear streams with rocky bottoms usually covered with dense mats or clumps of algae (Ref. 28731). This species produces small pyriform eggs, laid on the undersurfaces of stones in freshwater streams. Newly hatched larvae are small (0.12-0.13 cm in notochord length) and poorly developed. These migrate downstream to the sea shortly after hatching at dusk, where they develop as pelagic larvae for 2.5-5 months. Pelagic larvae may potentially disperse to distant islands before migrating to freshwater streams when they reach 1.3-1.4 cm standard length (SL) where they grow further and reproduce (Ref. 95104).
