Inhabits estuaries and the lower reaches of coastal streams (Ref. 44894). Occurs in lowland streams, forming schools that feeds at or near the surface on insects and zooplankton. Found among the annual Tasmanian whitebait migrations in shoals with Lovettia seali and various galaxiids. Most of the life cycle is spent at the sea (Ref. 44894). The species is thought to have an anadromous life cycle involving upstream migration of adults from the sea prior to spawning. Newly hatched larvae are carried on tides out to sea where they develop to maturity (ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6406 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.3 ±0.42 se; based on food items.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
