The Malabar danio (Devario malabaricus formerly Danio malabaricus) is a tropical fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka and the west coast of India, the fish has been circulated throughout the world through the aquarium fish trade. It grows to a maximum length of 6 inches, but rarely reaches past 4 in a home aquarium.(15.2 cm). The species was earlier incorrectly considered a synonym of Devario aequipinnatus, which is a valid name for a different species.
