Favia and Goniastrea corals are both members of the family Faviidae and are commonly known as brain corals due to their large, dome-shaped corallites resembling the folds of a brain. While they share some similarities, there are also distinct differences between the two genera. Generally favias have larger more irregular polyps that share the coralite walls, while those of goniastrea are smaller and more rounded, with distinct divisions between coralites. Both generally thrive under moderate lighting and flow, and benefit from occasional feedings.
