Scientific name: Mithracidae
Mithracidae, commonly known as Mithrax Crabs or Emerald Crabs, are a family of reef-safe crabs known for their algae-eating habits. They play a beneficial role in the aquarium by consuming hair algae and leftover food, which helps maintain water quality. These crabs are generally peaceful and can coexist with most tank inhabitants. They are nocturnal and often hide during the day. Providing ample rockwork and hiding places is essential for their well-being. Mithracidae species vary in size and color, with the Emerald Crab (Mithraculus sculptus) being one of the most popular in the hobby.
