High Quality Content by WIKIPEDIA articles! The danionins are a group of small minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera Danio and Devario. They are native to the fresh waters of southeast Asia. Many species are brightly coloured and are available as aquarium fish worldwide. Danio tend to have horizontal stripes and long barbels, Devario tend to have vertical bars and short rudimentary barbels, if barbels are present at all. All danionins are egg scatterers and breed in the rainy season in the wild. They are carnivores living on insects and small crustaceans.
