The Cherry barb is a peaceful fish ideal for a community aquarium with other non-aggressive fish species that appreciate the same type of environment. It is naturally important not to house Cherry barbs with predatory species that will consider them prey. A Cherry barb should always be kept together with at least 4 members of its own species. A school of Cherry barbs can be house with a wide range of docile fish species, such as Danios, Plecos, Bettas, Corydoras and Rainbow fish. Nippy fish species like the Tiger Barb should generally be avoided. The Cherry Barb is a very timid fish that should be housed with fish of the same temperament.
Some of the tank mates mentioned may not be suitable for your tank size but they will deffo go with your barbs.
