Fire corals seem to fare better than many other corals and are fairly common. Labeled MC ( mustard coral) in these photos, learn to stay well away from fire coral.. Don't go where you may brush against it. It will burn like a very bad jelly fish sting. If you know what fire coral looks like you will not hang out around it when you adjust your mask etc. !

FIRE CORAL IS MORE DANGEROUS THAN OTHER CORALS . DON'T TOUCH ANY CORAL, YOU WILL HURT THE CORAL BY REMOVING ITS' PROTECTIVE COATING.

IF YOU NEED TO ADJUST YOUR MASK ETC AND YOU ARE NEAR ANY CORALS LEARN TO TUCK YOUR KNEES UP IN FRONT OF YOU AND NOT KICK YOUR FEET AROUND BELOW YOU WHERE YOU ARE NOT LOOKING.
