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