I wouldn't remove a crab unless I caught it red-clawed eating a fish. And since my fish are pretty big, I leave crabs in the tank. Haven't regretted it in 10 years.

Looks like a crab from the mirthrax sp? Like an emerald crab just not green. I got 3 or 4 of those exact ones in my tank right now , they are shy and come out a night to graze . They eat bubble and hair algae in my tank so i dont see how there bad.
