Oceania: known only from Lake Kutubu and its outlet, the Soro River, in the Kikori River drainage of the Southern Highlands, Papua New Guinea.

Biology     Glossary (e.g. epibenthic)

Inhabits a highland lake and its outlet about 220 km upstream from the Gulf of Papua (Ref. 2847). An omnivore and egg laying species which is considered in the aquarium trade as a peaceful community fish. Prefers the following aquarium conditions: pH=7.3, H=12, 27°C water temperature, needs rocks, plants and driftwood cover (Ref. 6398).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (-0.30300 - 0.32300), b=3.04 (2.92 - 3.16), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.9   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100) .
Price category (Ref. 80766):   Unknown.
