Inhabits flowing streams and ponds in clear water, most common in creeks between ponds (Ref. 5259). Occurs in small, swiftly flowing, well-vegetated creeks in clear, cool water (14°-16°C), over gravel or cobbles. Often found around accumulated flood debris and log snags Feeds on aquatic insects and benthic microcrustaceans. Breeds from spring to early summer. First discovered in the early 1980s. Co-occurs with N. australis at Ewen ponds, but generally prefers faster flowing streams rather than ponds (Ref. 44894). Aquarium conditions: pH=7.2, H=8, 22°C water temperature, carnivore, egg layer, peaceful community fish requiring rock and plant cover (Ref. 6398).
