The Rosy Barb (Pethia conchonius) is an active, peaceful species well-suited for a community aquarium. It is considered one of the hardiest barbs, undemanding and beautiful, and most impressively colored during the mating period. It can be kept together with other small fish but can be aggressive toward other fish and nip their fins. They will eat most foods provided to them. They are best kept in groups of 5 or more in an aquarium with a length of at least 76 cm (30 inches). They usually reach a maximum size of 10.2 cm (four inches). Using a dark-colored gravel will show off the color of the fish.
