Lori,
Just take the rock out, the coral will be fine for a few mins while you use the super glue gel or epoxy...
I've found the best gel so far to be the loctite brand, althought I've heard good things about the IC gel they sell on ebay...
as for epoxy, I use the "Aqua-mend" from home depot, its $2.49 a stick and it doesnt mess my skimmer up for days like the "aqua-stick" from two little fishies does
Happy Fraggin
