Common name: Mud crabs
Scientific name: Xanthidae
Xanthidae is a diverse family of crabs known commonly as mud crabs, pebble crabs, or stone crabs. They are characterized by their robust and often brightly colored bodies. Many species within this family are popular in the marine aquarium trade due to their scavenging habits, which help keep the tank clean by consuming detritus and uneaten food. However, caution is advised as some species can be aggressive and may harm other tank inhabitants. They typically require rockwork or other hiding places in the aquarium to feel secure. Xanthidae species can also be sensitive to poor water quality, so maintaining pristine conditions is crucial for their health.
