Feeding corals

[Coralgurl]

WTH??? I fed my corals again last night, same response from them all. I have 2 acan frags sitting on the sand, check this morning, and 1 of the frags is a complete skeleton, nothing left of it???? I fed the fish first to make sure they weren't aggravating any of the corals, my shrimp are on the other side of the tank....

The frag had its feeding tentacles out and looked really good. Then bam, just gone.
