The Honeycomb Brain Coral, Goniastrea palauensis, is a brain coral with a distinct honeycomb pattern. They come in many different colors. The Honeycomb Brain Coral should be kept in an aquarium with moderate lighting and medium waterflow. It is important to place them far enough away from neighbors so their tentacles do not harm any other organisms. Like many other corals, they will take a supplemental feeding of brine or mysis shrimp one or two times per week.
