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. Ikan Wader is a common Javanese name for smaller freshwater fishes, especially cyprinids (already used in Old Javanese). See Blust, R. & Trussel, S. Austronesian Comparative Dictionary. Web Edition (https://www.trussel2.com/acd/); renata: From the Latin ren (kidney), alluding to the kidney-shaped throat marking.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9 - 11; Anal soft rays: 28 - 31; Vertebrae: 30 - 32. Characterized by having kidney-shaped black throat mark; dorsal and caudal transverse bars present; spotted opercle; opercle with black lower margin; subdorsal scale, mode 6 ½; postdorsal scales, mode12; anal fin rays, mode 29; and lateral scales, mode 31 (Ref. 56386).

Facultative air-breathing (Ref. 126274); Occurs in black-waters draining out from peat swamp forests. Also collected from a flooded peat swamp forest, among plant debris and logs in shallow tea-colored water, with a pH of 4.1 (Ref. 30225).

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 (0.00377 - 0.02651), b=2.97 (2.74 - 3.20), 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): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.
