SPS

Small Polyp Stony (SPS) corals are characterized by their compact, hard calcium carbonate skeletons and small, tightly clustered polyps. These corals are some of the most important reef builders in natural marine environments, forming extensive colonies that contribute significantly to reef biodiversity and structure. SPS corals typically require high lighting and strong water flow to thrive, making them more challenging to keep in aquariums compared to LPS corals. Popular among advanced aquarists, SPS corals, such as Acropora, Montipora, and Seriatopora, are admired for their intricate shapes and vivid colors, offering an appealing aesthetic in well-maintained reef tanks.
