Biology     Glossary (e.g. epibenthic)

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).

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).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (19 of 100).
