Perhaps one of the most attractive of all tangs, this species has a reputation for bossing almost every aquarium into which it’s stocked. The time taken to reach dominance depends on the size at which they are introduced and the other species present. Eventually they become the most dominant fish – which is fine, provided you don’t subsequently wish to add any species that the Purple tang might take exception to.
