Does this coral look sick to you? (Sorry about the dirty glass / iphone pic)
The two black holes in the flesh is what bothers me, what could have caused it? And what do you recommend doing to help nurture it back? A friend asked me to help, the only advice I can give really is to look for something maybe eating it / near it at night, and do a coral dip, possibly change 50% of the water, but I don't really see how that could help since this is the only coral in that tank not doing well.
