White/clear crab?

[twps]

Last night after the lights went out I scoped out my tank with a flashlight and to my surprise found a crab that I didn't intentionally bring home. It's small about the size of a dime, moves wicked fast, and his colouring appears to be almost white. I can't get a decent pic of him, or a close enough view to give a better description, it's hard to see his claws since they're so small also. It looks like he's nocturnal, since I haven't seen him during the day.

I'm assuming I'll have to wait to identify him as good/bad when I see his claws?

I wonder how long he's been in there... Any chance he could be the culprit for my MIA fish?

Maybe... I was missing one of my new Yellow Watchmen Gobys today. Looked everywhere couldnt find him.... upgraded my sump and found him in my sump.

If the crabs that small,I doubt he would have went after your fish.But that dont mean he wont when he grows up.
