Danio is a genus of small freshwater fish in the family Danionidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms.
This freshwater danio comes from northern India and surrounding countries, usually found in slow-moving ponds, streams, and rice paddies full of vegetation. They would enjoy a 20-gallon long aquarium (or longer) that has plenty of plants to simulate their native habitat, but don’t forget to leave lots of open space for swimming. A sponge filter with gentle flow would be appreciated, but the tank can be unheated since they are comfortable at temperatures of 65–75°F (18–24°C). Because of the seasonal monsoons, they are used to rapidly changing parameters and can easily handle pH of 6–8 and soft to hard water.
