Emerald Crab  (Mithrax sculptus)

The green mithrax or emerald crab is an excellent consumer of nuisance micro algae as well as some invasive species of macroalgae such as valonia (bubble algae) They're mostly nocturnal scavengers, hiding under rocks and rubble during the day. They're most useful when young as full grown emerald crabs can quickly consume large amounts of many species of desirable macro algae. Emerald crabs are reef safe and will not eat corals or gorgonians. We ship a size that is approx1/2" to 1". 

Use the drop down menu below to add multiple emerald crabs to the same bag to save on shipping cost.
