Crabs & Lobsters for Saltwater Aquariums

Reef dwelling crabs such as the red leg hermit crab, blue leg hermit crab, and emerald crab are all a part of nearly every reef keeper's cleanup crew. These cleaning machines help to keep the aquarium clean. Emerald crabs do not need to move from shell to shell as they grow, these crabs molt and grow their own exoskeletons which are a deep emerald green. Keeping some small empty shells ready in an aquarium is always a good idea when keeping hermit crabs, your snails will thank you for it and will live much longer.
