LPS (Large Polyp Stony) corals are generally larger calcareous corals with larger fleshy polyps than those of the small polyp stony (SPS) coral. They range in ease of keep from being some of the easiest to some of the most difficult of corals to keep. Some LPS corals also have long tentacles called sweeper tentacles which are used to ‘clear’ other corals away from their immediate vicinity.
