Will a pistol shrimp kill my fish or invert?
 

I want one, but can I put it in my tank? It's a 30L reef with a 3 inch deep sand bed.


Fish:
coral beauty
small black clown
lawnmower blenny

other animals:
2 peppermint shrimp
several hermits
emerald crab
several snails.

Also I have several soft corals and two condys.

Can I add one without the chance of it getting harmed or anything in the tank getting harmed. If there is a chance of it harming something, what is the something? Thank in advance for any help.

?

I have a 2" one in a tank with hermits, snails, peps, and a silly mandarin who doesn't understand right of way. I have seen it grab a hermit and move him. I have seen it click at one, but the impact hit the hermit's borrowed shell and did no damage. This is a tiger pistol with a yellow watchman.

How long has he been in there? Do you know if it make a difference on the type of pistol. The one at the LFS is a brown color and I think if I remember right it had yellow on the large claw. Anyone else have one, or know?
