Emerald Crab

This small spider crab is predominantly green. Unlike most of its kin, it neither decorates itself nor preys very often on living animals. Truly an oddity among crabs, it is mostly herbivorous. It seems to prefer adherent fleshy green algae, with will eat other types. This is one of the few aquarium animals that will eat bubble algae, which may occasionally reach plague proportions in some tanks. The Emerald green crab requires normal reef aquarium conditions, plenty of algae, and some rockwork, but is otherwise undemanding.

Generally reef compatible with a relatively reef safe herbivore, but there have been occasional reports of it attached sessile animals. Feed a mostly herbivorous algae diet, but also preys on small animals and will scavenge aquarium foods. (Credit - "Pocket Guide, Marine Invertebrates")
