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/).;  midas: The specific epithet is an allusion to the Greek Midas, a mythical king whose touch turned everything to gold, arising from the iridescent gold opercle and body scales. A noun in apposition..

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 8 - 10; Anal spines: 1 - 2; Anal soft rays: 25 - 29; Vertebrae: 31 - 32. Can be distinguished in possessing the following combination of characters: relatively thick-set body (body depth 24.3-29.0 % SL); head devoid of pattern except for black stripe that runs from black lower lip, through eye to edge of opercle; opercle with gold iridescent scales when live; belly and body with gold iridescent scales; some median caudal rays projecting beyond fin margin (Ref. 81926).

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); A paratype series was collected from a blackwater river running through remnant and intact peat swamp forest, with pH 4.1(Ref. 81926).
