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); khwae: Named after its type locality, Mae Nam Khwae Noi.

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.9 cm SL male/unsexed; (Ref. 46238)
Dorsal spines (total): 16 - 17; Dorsal soft rays (total): 8 - 10; Anal soft rays: 7 - 8; Vertebrae: 27 - 28. Possesses a dark blotch on the dorsolateral aspect of the caudal peduncle present. Postorbital stripe angled. Rounded caudal fin; blotch on caudal peduncle small and confined to the side of the caudal peduncle. Absence of a pattern of horizontal rows alternating light and dark stripes along side and absence of prominent dark spots in vertical bars or horizontal rows. Dark bar entirely across the caudal fin base with the dorsalmost portion darker and separated from the rest by light band instead of the 3 dark blotches in most Badis species. Scales in lateral row 27-28 (Ref. 46238).
The type locality was a small creek, 1-2 m wide, 0.1-0.3 m deep; sandy bottom with some aquatic vegetation, in a cultivated area; located in a deep groove, covered by trees. Also collected from a relatively large stream and from a spring fed reservoir, up to 2 m deep (Ref. 46238).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00501 - 0.02757), b=2.92 (2.72 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
