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/).; compuncta: From Latin word 'compuncta', feminine past participle of the Latin verb 'compungere', to prick, to puncture, hence the verb 'notis compungere', to brand, to tattoo, referring to the distinct black pattern on the body, usually in females; as adjective..

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 8 - 10; Anal spines: 0 - 1; Anal soft rays: 27 - 29; Vertebrae: 31 - 32. Presence of the distinct black reticulated pattern up to 5 scale rows in depth on side of body above anal-fin base in females and juveniles, black patch in males. Lower half of caudal fin and posterior half of anal fin in females with orange or yellow subdistal band when live, pale band when preserved. Anal-fin with 28-30 rays. Dorsal fin with 8-10 rays, no spine. Lateral line with 32-34 scales. Predorsal scales 21-23. Predorsal length 64.4-68.0 % SL (Ref. 57022).
Facultative air-breathing (Ref. 126274); Inhabits mainly slow flowing small streams in swampy areas of the heath forest, although it can also be found in faster flowing larger tributaries (Ref. 57022). Occurs in these habitats with very acidic waters due to the presence of subterranean and surface coal (Ref. 57022).
