An easy to care for fish the Rosy barb has a lot going for it. Feeding is never a problem as it will eat all flake frozen as well as live food. The tank should be fairly large as this like most barbs is an active swimmer and needs plenty of open spaces. Plant toward the rear and include some floating material if you desire. The Rosy will dig and forage in the gravel, so it should be fairly fine and rounded. A darker color will bring out the Rosy's coloration. Water conditions are not to critical as they will adapt to almost all variations, but they will benefit from aged water and of course the partial water changes we all make (or should be). Temperature is also not a problem as you see from the quick stats the range is large with somewhere in the middle being ideal. They spend most of their time on or near the bottom so make sure its tankmates swim near the middle or top of the aquarium to give the tank a balanced look.

Breeding the Rosy barb is fairly easy. The tank should be large and have a thin layer of gravel. Provide fine leafed plants for the eggs to scatter into. The water should be well aged and have a neutral pH. Place one male and two females in the tank. Spawning usually will take place in the morning and the females are the more active partners. They will chase each other around and the spawning will take place in one of the plants. The pair will wrap themselves around each other and shake until the eggs are laid. This will happen several times and the number of eggs laid can be very large. The parents are egg eaters and will eat the spawn if given the chance. Remove the trio immediately as they will start eating the eggs even during the spawning. The eggs hatch in about a day and the fry must be fed fine flake food or baby brine. Growth is rapid and the young are easy to care for. Keep up the water changes as the fry require better water than the adults.
