Choosing a tank location and tank mates for brain coral that minimize the risk of damage, target feeding it several times a week and providing the ideal living conditions allows this coral to thrive. Brain coral is an ideal invertebrate for both novice and experienced aquarists because its needs are relatively simple.
Brain coral prefers anchoring the base of its skeleton in sand or mud and sitting on a sandy substrate. If the coral rests on live rock, it can fall over when its polyp swells. Falling typically causes mechanical damage that increases vulnerability to disease, and it can fall into another sessile invertebrate, stinging it or receiving a sting from it.
Although brain coral can shed sand deposited on it, active sand-sifters and burrowers can cover it with sand faster than it can clear itself. Brain corals require adequate space between them to prevent stings when extending its feeding tentacles, and placing them in a tank with coral-feeding fish, such as triggerfish and butterflyfish, should be avoided.
Brain coral feeds on symbiotic algae that live in its tissues and larger zooplankton, and it typically captures some of the food added to the aquarium to feed the fish. Its diet can be supplemented with frozen mysid shrimp and small pieces of frozen seafood. They require high lighting, but lighting levels should be increased gradually to prevent photic shock. Brain coral prefers weak-to-moderate currents and temperatures of 74 to 84 degrees Fahrenheit.
