The Cherry Barb, Barbus titteya, is an egg-scatterer like most other barbs. The male is an active pursuer of the female and can get a bit rough with her. A well-planted tank is recommended. The female will swim around the tank scattering up to 300 eggs with the male following close behind to fertilize them. The eggs are adhesive and will cling to plants and other objects in the aquarium. The parents will eat the eggs pretty quickly so you might consider removing the parents once they're finished spawning.
Some people use breeding traps with considerable success with Cherry Barbs. Regardless of the method you use, if the eggs are successfully fertilized then you should begin to see fry in 2 to 5 days. They will feed on infusoria at first but should be able to take brine shrimp nauplii within a week and finely ground flake food within 2 weeks.
