Emerald crabs make up a member of what is commonly called 'the cleanup crew'. They scavenge the aquarium for leftover food or algae and help to keep a marine aquarium clean. One of their claims to fame is that they will eat bubble algae (valonia) which is a nuisance algae. They also devour hair algae and even Bryopsis if hungry enough. We recommend 2 crabs per 20 gallons. However, it all depends on how much algae is present as well as other algae eaters
