Goniopora and Alveopora corals are both members of the family Poritidae and are commonly known as flowerpot corals due to their polyps resembling flower petals. While they share some similarities, there are also distinct differences between the two genera, such as the tentacle count on the polyps. Gonis have 24, and tend to be longer, while alveopora have 12, which tend to be shorter and club shaped.
