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); chittagongis: Named for its type locality, Chittagong Hills, an adjective with alternative endings -is, -e..

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=0.00537 (0.00222 - 0.01301), b=3.05 (2.84 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec<100).

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