If you have lots of rock work and consistent water quality and are looking for an attractive clean up crew to help with algae and food remains, the emerald crab might be right for you. Relatively small and shy, you are unlikely to see them during the day. On the flip side, they are relatively unlikely to eat your other inhabitants as far as crabs go, although of course they will try. They are crabs after all.
