Morphology | Morphometrics
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).
