Yes get 2 if your tank is mature and the crabs are compatible, but they may not eat the B.A.
another way to get rid of it and it worked for me is during water changes. Take your siphon hose while is siphoning, and rub the algae off the rock, but then try to suck up the algae and hopefully anything else if it popped.
