I have a sneaky predator

Hey guys:
I have a small 5 gallon aquarium with 5+lbs of live rock, a few corals, a single hermit and two snails. I USED to have a little goby and a peppermint shrimp.
A month or so ago my goby mysteriously died and I had to move some of the rock around to pull it out... it was pretty wedged in there. It looked a bit tattered. Yesterday my shrimp disappeared without a trace... no body, nothing. Just gone. My aquarium is pretty small so it's very easy for me to check all possible places.
I didn't understand the goby but I thought that maybe a water change had gone wrong and left it at that. I didn't replace the fish because I am going to be gone over the holidays and if I don't have a fish I don't need someone to come feed as often. The shrimp is a real mystery as it has disappeared completely.
I will not be getting any other fish until after the New Year, but now I am concerned that I have something preying on my fish. I just don't know how my rather large shrimp could have disappeared without even a leg being left over.
Because it is a small tank, I just don't know how something that can take out a whole fish can be lurking in there. The only suspicious thing I have seen is a small brown lobstery thing that has popped out of a rock (only twice in 5 months). I am pretty confident that it is not a mantis shrimp because it has two distinctive claws, one bigger than the other. It is about an inch long, very quick.
I don't want to remove the rock he is in because that would be about half of my display. I don't even know if he is the culprit. Any ideas?

Mantis??? try making a bottle trap and baiting it shimp pieces.
Take a 20 ounch soda bottle, cut off the top, and invert it in the bottom, secure it with super glue.

Get a flashlight, go to your local craft store and buy some red thin plastic film. Tape the film over the lens and use your home made red light a few hours after you turn off your tank light and see who comes out to visit

Google "Pistol Shrimp"

He is a very plain ugly thing, not at all colorful like a lot of the pics I'm seeing of pistol shrimp. It looks a lot like this thing:

The thing is, he lives in a live rock and does not burrow in so far as I can tell. I also have never heard in clicking/banging noises. Are pistol shrimp aggressive? Would they eat a peppermint shrimp?

Looks like a tiger pistol to me:https://www.saltwaterfish.com/site_11...ot_parent_id=4

As of right now I am skeptical that it is a pistol shrimp so I'd like to keep this post going to find out if it is something I should worry about... the larger claw isn't nearly as prominant as I am seeing in all of the pictures and it has no pattern what-so-ever on it's body, it's just plain boring brown. He also is living inside of a rock, rather high off the sand bed, and not burrowing. Isn't it a key characteristic of pistols to burrow in the sand? I still have a peppermint shrimp missing so something ate it. I forgot to mention because it's been so long ago, but I used to have two more hermits and two more snails.
I'll be keeping a camera handy and watching the tank carefully tonight after lights-out.
Thanks for all the ideas so far!
