Emerald Crab (Mithrax sculptus)


The Saltwater Emerald Crab is a great addition
to any aquarium and is reef safe. They eat bubble algae and are very
easy to take care of. Ample food needs to be present for them though as
they will clean all the bubble algae out of the aquarium. Supplementing
seaweed or chopped meaty food will suffice for
them. They are also scavengers and will clean out most organic debris
from the aquarium.
