Description

The Emerald Crab (Mithraculus sculptus) is a popular addition to many saltwater aquariums due to its attractive, vibrant green color and beneficial algae-eating habits. This hardy crustacean is known for its unique ability to control nuisance algae, including bubble algae, making it a useful tank inhabitant. The Emerald Crab’s flat, smooth, emerald-colored body and claws allow it to blend well into live rock structures, providing both natural camouflage and a sense of security.

While generally peaceful, the Emerald Crab may exhibit semi-aggressive behavior, especially if food is scarce. They are typically reef-safe but should be kept with caution as they may pick at corals or small invertebrates if they are hungry or lack algae. For the best care, ensure they are provided with plenty of hiding places and supplement their diet with meaty foods like mysis shrimp or algae-based foods if natural algae sources are insufficient.

These crabs are active foragers and tend to explore their surroundings, often becoming bolder in a well-established tank. Emerald Crabs are relatively easy to care for and adapt well to a range of water conditions, making them suitable for both beginner and experienced aquarists.
