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