Barb Species Habitat and Care Information

Barbs are lively, hardy and colorful fish. They are an all schooling species that do best if kept in groups of at least five or more, so keep that in mind when considering this family of fish. Most prefer soft acidic water that is well aerated and a bit on the cooler side.

Because Barbs are so active, tank mates should only be species that can tolerate boisterous companions. Long-finned fish, in particular, are usually not the best tank mates for members of the Barb family. The following Barb species overviews will help you choose one that is right for you.
