Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Temperate; 10°C - 30°C (Ref. 2060)
Oceania: endemic to Australia.
Length at first maturity / Size / Weight / Age
Maturity: Lm 3.3 range ? - ? cm
Max length : 8.5 cm TL male/unsexed; (Ref. 44894); common length : 6.0 cm SL male/unsexed; (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).

50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00400 - 0.02738), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

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