Crab ID - possible Hitchhiker?

[TotalKhaos]

I have 100 lbs of LR in my tank - 40 lbs was purchased within the past 2 weeks.

I purchased 10 hermits - 5 red legs, 5 blue legs. I inspected each hermit and None looked anything like this one.

This one resembles the blue and red legs in all way except that its grayish green in color and the claws look slightly larger. I found this one grazing on a rock and I know I didnt put him in the tank. Anything I should be worried about?

Edit/add: looking at him harder I noticed him burrowing under a piece of rock rubble - nothing I've ever seen out of my other hermits. sorry such a bad picture, I need to learn how to use my camera.

Thanks!
