Épines dorsales (Total) : 8; Rayons mous dorsaux (Total) : 9 - 10; Épines anales: 3; Rayons mous anaux: 7 - 9.

Occurs in small, slow-flowing streams and swamps where there is dense aquatic vegetation (Ref. 5259, 44894). Tolerant of temperatures between 25° and 38°C, and a pH range of 4.5-8.1 (Ref. 44894). Feeds primarily on aquatic insects and micro-crustaceans (Ref. 5259, 44894). The smallest ambassid in Australia, with a life span of probably 2-3 years. Sexual maturity is attained at the end of the first year and breeding has been recorded in the wet season in flooded swampy lagoons (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00496 - 0.02782), b=3.02 (2.82 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.45 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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