What type of crabs

Well my tank is almost a year old now and I want to add some more crabs, ive got my standard blue legs running around but I want to consider gettign the big mama jama's maybe 2 to run around the tank or a realy crab. I want to get these as to clean up what the fish dont eat., i have alot of little areas my fish cant get to and wanna do something. Remember these have to be reef safe. Let me know what you guys think. All my info is in my sig.

Could do emerald crabs.

 

reef safe crabs good luck

 

emeralds...cud do ad.ecorator if you can deal with their moving habbits. porclin crabs will be good too but i believe they filter feed.

boxer crabs are cool but idk how reef safe they are,i thi k they r.

 

The only truly reef safe crab is a porcelain crab, but they aren't going to be cleaning up uneaten food.

My suggestion would be to feed less or slower so that all the food is eaten by the fish.
