Common names: lobed brain coral, open brain coral
Natural origin: Indo-Pacific
Sensitivity (Level 2): These corals are generally tolerant, but need to be fed well.
have impressive prey capture ability. They will ready eat a variety of
meaty aquarium foods. Be forewarned, they can even eat small aquarium
Lighting (Level 4 to 7): These
corals seem to prefer moderate lighting. They can adapt to more intense
lighting if allowed to do so slowly over time. As with most all corals,
sudden changes in lighting can cause bleaching.
Water flow: Moderate to stronger water flow is ideal.
are very aggressive corals best placed in a sand or rubble bottom. Give
them plenty of room. Sometimes tangs and hermit crabs will nip at
and/or irritate the coral's soft tissue. Keeping the tank well fed
can help prevent competition for food.
Slow tissue recession can be a sign of starvation. Though these corals
have impressive feeder tentacles, in captivity, it may take them some
time to get "settled in." If after several weeks you still do not
observe an extension of feeder tentacles, you can try to encourage a
feeding response with night-time target feeding. One hour after the
lights go out, turn off circulation during feeding so that the food can
fall onto the coral. Give the coral an hour or two to "grab hold" of the
food, then turn the water flow back on. Do this daily (or every other
day) until feeder tentacles extend regularly in anticipation of feeding.
