Producing stinging sweeper tentacles, the 'Elephant Nose
Coral' (as it has been commonly dubbed) should be kept a good distance
from both soft corals and stony coral neighbors. Mycedium are most often
plating corals, with raised bumps
somewhat resembling noses (although not elephant trunks, as the name might
suggest). These corals are most often found in browns and grays, although
blue, yellow and red specimens have also been known to occur.
