Etymology: Betta: Malay/Javanese origin. Bleeker (1850, 1858) indicates Ikan Wadder Bettah as the local name of Betta trifasciata Bleeker, 1849 (now Betta picta , Valenciennes, 1846) in the Ambarawa Javanese dialect.

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 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 ):  3.3   ±0.4 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Produces a minimum of 100 eggs (Ref. 1672 )). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
