random goby death

[iceman86]

I bought a sleeper goby who looked healthy last week from a lfs and 3 days later it died. I have a perfectly healthy tank with a ton of corals from softies to sps. Tank has been up for 10 months, 35 gallon cube, 15 gallon sump, and all the neccesary equipment. and it has about 3" sand bed. I also have 2 clowns and a coral banded shrimp.

The goby was swimming around from the second I put him in after acclimating him for 45 minutes. The goby didn't just pick up sand with his mouth he would actually dig holes in the sand and under the rocks to the point that the rocks fell over. Could it be possible he disturbed the sand bed so much that something came up? Nothing else was harmed in the tank.

I also spotted the shrimp trying to nip at him a couple times every time he swam by the shrimps "hangout" could the shrimp be the culprit?

Any ideas?
