Acropora are abundant, diverse corals that live in most of the world's reefs -- forming large communities in pristine clear ocean water. 

Acropora are grouped by aquarists as small-polyped stony (SPS) Scleractinia corals in the scientific class Anthozoa. These reef-building colonies are usually branching, bushy or plate-like. They have the largest variety of growth forms of any coral, often found with complex branching and light skeletal forms. Many species have bulb-shaped, colored corallites that appear in bright colors at their tips. Their mixed shapes and sizes create a wonderous array on ocean floors and in aquarium displays.    

These stunning corals fascinate collectors who trade photographs to share the multi-color dimensions that appear across branches and tips of the Acropora.
