Shrimp and Snail ID

[clown52]

I got a new tank but its former owners had a couple inverts with it. I need to get an ID on these guys since I will be setting the tank up as a reef.
I want to know if the pistol shrimp will accept a gobie. I would also like to know what the giant snail is, he spends most of his time buried in the sand.
The shrimp is about an inch and half long and the snail is almost the size of my fist.

Looks like just a common pistol shrimp. Hard to say if that type will pair with a goby but you can always try! Watchmen work well.
That looks like a conch to me but I'm no expert on that. It looks like what we commonly see here in FL.

That is a kings crown conch and is a Predator.

The couple I got the tank from was from FL and moving back, they didn't want to move the tank again.
So by "predator" I am guessing I need to find a new home for this guy asap? Everything I see just mentions them eating other snails, would they eat other inverts like my shrimp?
