The Merulina Coral will need a high light level and placement at mid-level or higher in the aquarium with a medium water movement. While it rarely exposes its polyps, they may occasionally be seen at night. The sweeper tentacles that are used to gather food will reach about three inches in length. It is, therefore, a good idea to keep other corals outside of this range. For continued good health, it will require the addition of calcium, strontium, and other trace elements to the water.
It will benefit from additional food in the form of micro-plankton or brine shrimp twice a week.
