Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); Inhabit quiet pools and backwaters of creeks and small to large rivers, swamps, lakes and overflow areas of large streams. Often occur near vegetation and submerged logs. Feed on other fishes and insects. Spawning occurs over vegetation or other submerged objects (Ref. 10294).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5781   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00186 (0.00084 - 0.00412), b=3.20 (3.00 - 3.40), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (55 of 100).
Price category (Ref. 80766):   Unknown.
