Barbs are egg scatterers that do not tend their eggs or fry and so a separate spawning/fry tank is needed. Spawning usually occurs between pairs, but in some species, one male may spawn with a group of two to three females.
There are few visual differences between males and females, usually males are more colourful than females and less plump. To bring the adults into breeding condition, plenty of frozen foods should be included in their diet, and the water should be kept soft and slightly acid. Fine leaved plants or an artificial spawning mop should be used to collect the eggs. A bare bottom is recommended so that the tank can be kept very clean. After spawning the parents should be removed.
The eggs take between 1 and 2 days to hatch. Very fine live foods, e.g. infusoria, are usually needed to raise the fry. Frequent feeding is important, as are daily water changes to keep water quality high.
Water setup: 74-79°F; pH 6.
