Orange Acan- Acanthastrea echinata

Genus: Acanthastrea.

Acanthastrea (ack’-an-thass’-tree-ah) is a pretty common coral in the wild.

These corals look very much like other brain corals. These tend to have thicker tissue and typically grow cerioid (corallites have shared fused walls).

This was sold as an orange “Acan”, however the majority of the coral lacks the orange color. Oddly the color is spotted throughout the coral with some corallites being partially orange.
