Badidae (Chameleonfishes)
Etymology: Badis: 'badis' is presumably a Bengali local name, possibly derived from 'bhedo' or 'bheda', but it lacks a proper reference. Probably incorrect etymology (J. Müller, pers. comm., April 2021, after information from native speakers).

Max length : 7.1 cm TL самец/пол неопределен; (Ref. 102851); наибольший вес (опубликованные данные): 2.58 g (Ref. 111603)
колючие лучи спинного плавника (общее число) : 15 - 17; членистые (мягкие) лучи спинного плавника (общее число) : 7 - 10; членистые (мягкие) лучи анального плавника: 6 - 8; позвонки: 26 - 28. The species has conspicuous dark blotch covering superficial part of cleithrum above pectoral fin base. Lacks a dark caudal peduncle blotch. Body depth 30.7-38.9%SL; interorbital width 6,5-8,3% SL; scales in lateral row 25-27; circumpeduncular scales 19-20; pectoral rays usually 12. Has a series of prominent dark blotches along dorsal fin base and/or a series of dark blotches along middle of dorsal fin; and has indistinct bars on side. Has a distal extrascapular (Ref. 46238).
Occurs solitarily in rivers, ponds and ditches. Also found in swamps (Ref. 1479). Feeds on worms, crustaceans and insects (Ref. 7020). Used for behavioral studies (Ref. 4537). Length indications of up to 8 cm in some publications are exaggerated (Ref. 89918).
Produces 30-100 eggs. Distinct pairing with embrace (Ref. 31218).
