The Emerald Crab is most commonly known for its use in the Marine Aquarium to consume bubble algae and other types of nuisance algae.
The appearance of the Emerald Crab is a characteristic flat shiny Emerald Green shell and hairy legs, the Emerald Crab also has cupped claws that allow it to easily pull algae from rocks and other surfaces. This is a small species of crab normally getting no more than an inch and a half in length.
The Emerald Crab is native to the Caribbean, Gulf of Mexico and Atlantic. They are a peaceful tank mate that will not be a bother to most other inhabitants but has been known to eat certain types of coral as will most scavengers. Keeping Emerald Crabs with aggressive or predatory fish may keep them in hiding so they will never come out to graze at all.
