Shrimpt hitchhiker ID

[Brekett]

Anybody know what kind of pistol shrimp this guy is? He's been clicking away in my tank since day one, surviving a cycle and my MANY rock rearrangements.






Sorry for the blurry photo, best I could do. He doesn't like to sit still! Shortly after taking this I watched him take down a small crab that didn't take the hint about his burrow.

Really like him, but a little worried he's one of the more aggressive types. Any ID input would be really helpful. Thanks.

clicking away most likley a pistol shrimp but that's a guess since cant see picture

Yeah, it's definitely a pistol. Just wondered what species. Would like to pair it with a goby if possible.
