Blue legged crabs are aggressive, the will kill off each other and target snails for their shells. Try to get Red Leg Hermits instead, less agressive with each other and other inhabitants.
Also don't waste your money. 50+ crabs is an insane amount along with everything else. You'll end up having to 'target' feed all that clean up crew or they'll starve.
Remember the CUC will only assist you in keeping your tank in good condition, they won't make your tank maintenance free, even over compensating their numbers won't work.
Good luck.
