# SPS CORAL

SPS coral is the name given to the group of coral species that have a stony calcium carbonate skeleton with tiny coral polyps. These corals are generally the first that comes to mind when someone joins the reef aquarium hobby, sometimes called the ‘true’ corals because they are the corals that build the backbone of the reefs. But even though an SPS coral tank may be the first thing thought of, they are often the last coral species to be mastered.
