hairy crab.. grrrr

[BCWolfen]

I have a hairy white guy right now thats been crawling around my tank. I usually do a flashlight walk around midnight to see whats going on.
All I ever see him doing is eating algae. Haven't seen any of my softies damaged or missing snails (of course this may change)
But as I've read on wet web media regarding unidentified crabs...."innocent until proven guilty"
I do plan to try and capture him and move him to my fuge once I get my sump...in the next few weeks.
But until then...I will stay the squishy hammer unless he munches something he shouldn't
