Digitate coral
Acropora digitifera
CoralMarine
Its colonies form dense clumps of thin, digitate branches, often brown, green or bluish. Branch tips are rounded. It grows quickly and can dominate shallow reefs. Its polyps are small and retracted during the day. It reproduces by natural fragmentation. In aquariums, it requires strong light and moderate to strong flow. It is sensitive to parameter fluctuations.
