The Emerald Crab, Mithrax sculptus, are one of the most popular marine crab species for the home aquarium. They thrive in tanks with plenty of live rock and a sandy substrate as the like to graze searching for algae. As voracious algae-eaters, they can be incredibly beneficial members of a cleanup crew. If there is not enough algae or seaweed, they can be supplementally fed with prepared meaty foods. They should, however, be fed regularly to keep them from becoming aggressive towards their tank mates. Emerald Crabs are particularly effective against bubble algae. There is a reason emerald crabs are so popular; they are very easy to care for, require almost no attention, and are effective in in controlling pesky algal blooms hence keeping the tank clean.
