Have had the 7 gal nano set up for months. Today, while feeding the two fish in the tank, I noticed a hairy crab with a big purple claw in one of the holes in the LR

Don't exactly know how I missed it all this time, but don't want it in such a small tank. Heck, I don't want it even in my bigger tanks
Will try to catch it tonight. Wilty, you crab loving soul, want this crab if I can catch it?
