Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 4 - 6; Rückenflossenweichstrahlen (insgesamt) : 6 - 8; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 9 - 12.

Inhabits small creeks, swampy marshes, heavily shaded rainforest streams, lily lagoons and backwaters adjacent to major water courses. Usually found in Pandanus-lined creeks with muddy bottoms. Aggregations are encountered in areas with abundant vegetation and submerged log debris (Ref. 44894). Occurs at temperatures and pH ranging from 23°-30° C and 5.2-6.7 respectively.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Preiskategorie (Ref. 80766): Unknown.
