It is a hardy, semi-aggressive coral that will extend sweeper tentacles at night, and therefore, needs to be provided with ample space between itself and other corals in the reef aquarium. It requires a high light level and strong water movement within the aquarium, along with the addition of calcium, strontium, and trace elements to the water.

It will benefit from additional food in the form of micro-plankton or brine shrimp fed in the evening when its tentacles are visible.
