Emerald Crabs ar excellent algae eaters. They will concume a lot of hair algae. The Emerald crabs are masters of clinging to and hiding on and around rocks. They are primarily nocturnal in nature and may be difficult to see during most daylight hours. You will definately know they are there due to the amount of algae they will consume.
