One of my female albino tiger barbs is being chased around the tank. The rest seem to be swimming underneath her then swimming away really quickly as they do when they get food in thir mouths.
Does anyone know whats happening?

Sounds like mating behavior to me to, tiger barbs can be very nippy though so it could just be typical agression between them, how many tiger barbs to you have ?
