The blue perch (Badis badis) is a species of fish the in family Badidae of the order Perciformes.[1] It is a small, predatory fish that feeds on tiny invertebrates. Maximum length is around 8 cm. Sexual dimorphism is minimal, though males normally display stronger colouration and females may appear more rounded when gravid. Colouration is extremely variable and changes with mood, though typically the fins are blue and dark vertical bands are apparent on the flanks.
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.[2]
Badis badis is of slight commercial value as an aquarium fish.
