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

Very special thanks for the first photo of Symphyllia hassi to Dr. Douglas Fenner, American Samoa!
Colonies are hemispherical to flat and are seldom more than 0.2 metres across. Valleys are short and usually less than 25 millimetres wide. Walls are thick and in extreme cases can have an ambulacral groove which is wider than the valleys (similar to the faviid Diploria labyrinthiformis). Costae and septa are both thick. Septa have large blunt spines. Columellae are large and centred in valleys.
Habitat: Exposed upper reef slopes and reef flats.
