Short description Morfologia | Morfometria

Spine dorsali (totale): 1 - 2; Raggi dorsali molli (totale): 9-12; Spine anali 2-3; Raggi anali molli: 24 - 28. Belongs to the Betta coccina species group but can be distinguished from the remaining species of this clade by having bright, greenish-colored flanks and unpaired fins (vs. body blackish without iridescent scales, or greenish iridescent scales restricted to the lateral blotch or the central parts of the flanks). Diagnosed from its geographic neighbor species Betta uberis by having 10-12 dorsal-fin rays (vs. 14-17 in B. uberis) (Ref. 93322).

Facultative air-breathing (Ref. 126274); Found in peat swamps with depth of about 5 to 50 cm and with no water current. The water was shaded by trees and bushes. Collected among the aquatic and marsh plants. Forms bubble nest based on aquarium conditions (Ref. 93322).

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=0.01000 (0.00376 - 0.02663), b=2.97 (2.75 - 3.19), 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

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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