Snail killer! Help identify crab.

[Highside]

I have had a snail sitting on my frag rack for two days so I decided to check him out. He was dead but upon further inspection there was a crab inside his shell. The snail was still intact but the crab was behind the body of the snail. Got some pics. Any ideas?

that's crazy....it looks like an acro crab, but they are harmless. If you can't ID him, do you have a Fuge to put him in?

maybe baby mithrax or stone crab?

It appeared that this crab was the cause of death for the snail. For that reason he has gone to the city fuge.
