Rasborasare freshwater tropical fish belonging to the minnow family, that originate from Asia, in particular South East Asia. Generally Rasboras are hardy and make good aquarium inhabitants especially when kept in larger schools of 5 or more. Rasboras do best in a tropical aquarium of at least 40L, kept at 25-27°C, with a pH of 6.3-7.0 and KH of 5.

Fish that coexist with Rasboras in the aquarium include other species of barb, tetras, corys, gourami and other community fish that thrive in a tropical environment. Rasboras are omnivores and will accept most flake foods such as Sera Vipan and pellets such as Hikari Micro Wafers, but should also have some small foods such as frozen brine shrimp or bloodworms to supplement their diet with.
