The offspring of Acropora nana are possible. Unfortunately, the number of offspring is not large enough to cover the demand of the trade. If you are interested in Acropora nana, please ask your dealer for offspring. If you already own Acropora nana, try breeding yourself. This will help to improve the availability of offspring in the trade and to conserve natural stocks.
