General Description: The Emerald Crab is a popular addition to marine aquariums for its enthusiam to scavenge and control algae. Originating from the Caribbean, Emerald crabs are often green in color however, some red individuals make their way into the hobby. On average, Emerald crabs grow up to 2″ in size. They are particularily respected for their ability to clean up or control nuisance bubble algae. A nocturnal animal, Emerald crabs may not be seen frequently throughout the day until it is familiar with its surroundings.

Diet Requirements: Emerald crabs are omnivores. They will scavenge on various food leftover in the aquarium, in addition to consuming various algaes (i.e., bubble, hair). When food is scarce, crabs become opportunistic feeders and may nip at corals or predate on other invertebrates and fish within the aquarium. We recommend supplementing sheet algae and pieces of meaty foods occasionally to ensure Emerald crabs remain compatible with the reef environment.

Tank Requirements: An established, minimum aquarium size of 15 gallons is recommended to house an Emerald crab. Maintaining stable water parameters is a component to the success of keeping this invertebrate; Emerald crabs are intolerable of high nitrates. Creating crevices or caves with liverock will mimic the Emerald crab’s natural environment. Multiple individuals of Emerald crabs can coexist, but be sure there is ample aquarium space to reduce competition. While it is generally safe to add Emerald crabs into a reef aquarium, keep in mind that many crabs and shrimp are opportunistic on other slower moving invertebrates if their dietary requirements are not being met. Recommended water conditions: 76-78° F, dKH 8-12, pH 8.1-8.4, salinity 1.024-1.026.
