Badis badis, also known as the blue perch or blue badis, is a small species of Asian freshwater fish in the family Badidae of the order Anabantiformes. It is found in ponds, rivers, ditches and swamps in northern India, eastern Pakistan, Bangladesh, Bhutan and Nepal, including the Ganges, Brahmaputra, Mahanadi and Indus basins. It is sometimes kept as an aquarium fish. It is a small, predatory fish that feeds on tiny invertebrates. Maximum total length is around 8 cm (3 in). It is sexually dimorphic, with males growing larger and more colorful, especially when excited, compared to females. Adult males have blue fins and may display dark vertical bands on the flanks, while the smaller females display little color. Several similar relatives, now recognized as separate Badis species, have historically been confused with Badis badis. Historically the two genera that now make up the Badidae, Badis and Dario, were placed in the family Nandidae; this is no longer the case.

diagnosis
Diagnosis. Kullander & Britz (2002) redescribed Badis badis based on more than 200 specimens from the Ganga, Mahanadi, and Brahmaputra drainages, and fixed a neotype from the Tumapao [= Duma Baor] River in the border region between Bangladesh and India. Badis badis is similar to other species of the B. badis species group, characterized by a dark blotch on the exposed part of the cleithrum, absence of a dark blotch on the opercle, and sides of body with irregular narrow dark vertical bars formed by dark spots on scale bases. Badis badis has relatively wide interorbital space (Tables 2 – 5, Fig. 6), relatively few scales in a lateral row and dorsal-fin spines compared to B. chittagongis, B. pallidus and B. rhabdotus (Tables 6 – 7). Specimens from Nepal have a high frequency of 17 dorsal-fin spines, samples from elsewhere modally 16 spines (Kullander & Britz 2012: table 16; Blair et al., 2018: table 4). Preserved young specimens and females show the prominent pattern of narrow vertical bars; large males may be black, but with white scale centers arranged in rows or irregularly. The most similar species may be B. kanabos from the Brahmaputra River drainage, which is distinguished by a
