It crawled off of the bright pink frag I got today and went straight onto the clam and on the mantle. I am pretty sure the pink frag was dyed, this thing is the same color , even though the pictures don't show it:
I stuck him in a wine glass until I determine if he is harmless or not.
If you can't tell from the pictures, it looks like half of an oyster shell, and he had two little antenna.
