A wonderfully coloured Diaseris plate coral ,the  toxic outside edge makes thsi glow in the dark ! The frag you will receive will be around 25-30 mm segment  from the very species pictured . This species is happy on the substrate and will add something a bit different to your reef aquarium as it is very rarely found in this country and will be a bit of a rarity in your reef. It will grow in a disc shaped formation and is fairly easily kept in the reef aquarium.
