SPS Coral
Small Polyped Stony corals have small polyps on a calcareous skeleton. In many instances they are either branching or plate. The skeleton of these corals is slowly secreted by the epidermis at the base of each coral polyp making them the builders of calcium carbonate reef structures found in the wild.
SPS are generally considered more difficult to keep than the LPS and are not recommended for beginners. So please don't forget to research more information and care tips if this is a new type of coral for your personal collection.
