coral bleaching or dying?

[cooksalot]

i bought a new piece of coral on wednesday. it is some kind of brain moon...the center circles were all bright green...

now i've noticed that four of the green centers have turned white. i thought it might be sand, so i tried blowing it off, but nothing came off. is this bleaching? or could something in my tank be eating it, or is it just dying. the known critters in my tank are:

2 orange cat's eye snails
3 nassarius
4 cerith
two scarlett hermits
one emerald green crab

ok, just updated this with a picture..not great, but you might be able to get the idea on the left side of the coral:

anyone have any ideas and suggestions?
thanks!
