They prefer a well-planted tank of at least 30 gallons with soft, slightly acidic water. Rocks and driftwood can be added to the aquarium, but leave plenty of space for swimming. The Rosy Barb is a schooling fish and enjoys being in numbers. If in a large enough school, they typically will not bother any other fish in the aquarium.
It is best when trying to breed the Rosy Barb, to house two females with one male. Provide coarse gravel in the breeding tank and after the eggs have been laid, remove the parents. The fry will hatch in approximately 3 days, at which time, they should be fed baby brine shrimp until large enough to accept crushed flake food.
The Rosy Barb needs to be fed a variety of foods including vegetables as well as meaty foods. Feed a quality flake food as well as live and frozen foods such as brine shrimp and bloodworms.
