Poritidae

Porities sp. in a coral reef in Bermuda

The Poritidae are a family of stony corals ( Scleractinia ). They are the main Riffbildner addition to Acropora and usually grow in crusty or massive, round sticks. Only a few species form branchy structures. In the Great Barrier Reef, there are corals of the genus Porites that are over six feet tall, and its age is estimated at over 200 years.

In saltwater aquarium types of Poritidae are delicate and difficult to maintain.
