Enjoy the presence of Rosy Barbs as they thrive in a school, creating an excellent display in your tank with other like-minded community fish.
Rosy Barbs are hearty eaters and will enjoy a variety of foods including vegetables but also meaty food. Try a varied diet of plant matter, insects, flakes and pellet foods. They will eat any live foods so long as they can fit in their mouth. Also, boil some zucchini and peas as a treat. They will likely graze on any hair algae growing in your aquarium too. All you have to worry about when it comes to feeding them, is overfeeding. Rosy Barbs are schooling fish and need to be with no less than six others of their kind. If kept alone, Rosy Barbs will become stressed. Rosy Barbs are known to have aggressive tendencies and fin-nipping behaviour. So avoid housing them with slower-moving and long-finned fish; keeping them in larger schools curbs these behaviours.
When in decent sized schools, Rosy Barbs make excellent community fish. They socialise well with other non-aggressive fish. There are studies of success with Rosy Barbs housed with cichlids as dither fish. Meaning they help reduce innate timidity, aggression and promote normal social behaviours in other fish housed with them. A lid will need to be kept on your tank at all times, as Rosy Barbs are good jumpers and will likely try to escape. Rosy Barbs can also handle a range of water parameters if kept consistently. And are known to handle higher levels of nitrates. Live vegetation is a good choice for décor, but avoid soft-leave plants, as they will not survive with Rosy Barbs around.
As Rosy Barbs mature, the male becomes redder and slender. The female remains smaller and plumper. Females are also more yellow, olive, and gold in their colourings. Their ideal breeding tank is only a few inches deep in water, with plenty of vegetation. When hatched, move the fry to a different tank with more water, or you will see their growth stunted. Move adults to another (or back to the original) tank, otherwise, they will eat the fry.
