Engineer goby missing!

Your live rock probably ate them. When they go to die they usually go right underneath rocks and burry in the sand, or right inside holes of the rock.

I bought a huge lot of dried live rock once, and found a 4" dried up Blue Tang in one of the pieces. I Pm'd the seller and he said that he never even had a blue tang... so who knows how long it had been in there.
