Oceania: endemic to Australia.

Length at first maturity / Taille / Poids / Âge

Maturity: L_m 3.3 range ? - ? cm
Max length : 8.5 cm TL mâle / non sexé; (Ref. 44894); common length : 6.0 cm SL mâle / non sexé; (Ref. 44894)

Occurs in lotic and lentic freshwater bodies (Ref. 7300). Inhabits vegetated margins of streams, billabongs, drains, dams and swamps in still or gently flowing water. Forms small groups and is a very common prey item for introduced fishes, such as the Redfin perch and trout. Feeds on small crustaceans, insects and their larvae. Breeds from September to January, when water temperatures rise above 16°C. Reproductive habits and biology are typical of the family. Maximum life expectancy is about 5 years (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00408 - 0.02815), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Generation time: 1.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (tmax=5; Fec=78-679 (batch fecundity)).

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).
