The barred danio (Devario pathirana) is a fish belonging to the minnow family (Cyprinidae).
Originating in Sri Lanka, this fish grows to a maximum length of 2 inches (6 cm).
In the wild, the barred danio is understood to be critically endangered, but is freely available from captive-bred stock.
Its diet consists of annelid worms, small crustaceans, and insects.
The barred danio is oviparous (an egg layer), and is found mostly in the Nilwala River basin.
