Barbs are a diverse group of freshwater fish native to various regions across Asia and Africa. Known for their lively behaviour and hardy nature, barbs are a popular choice among both novice and experienced aquarists. Barbs are schooling fish, meaning they prefer to be kept in groups of six or more, which helps reduce aggression and encourages natural behaviour. An interesting fact about barbs is their ability to communicate through body language. They often engage in “shimmering” displays, where they vibrate their bodies rapidly as a form of social interaction, courtship, or establishing dominance within the group. This behaviour adds an extra layer of intrigue for Australian aquarists observing the social dynamics of their barb community.
