Assorted Crab

Calappidae crabs are commonly found in tropical and subtropical coastal waters and reef environments. They inhabit shallow waters and can often be found on sandy or muddy substrates, where they can use their camouflage to hide. These crabs are opportunistic predators and scavengers, feeding on a variety of small marine organisms such as worms, mollusks, and crustaceans. Calappidae crabs are known for their interesting behavior of folding their large front claws over their faces when they feel threatened or disturbed. It's essential to avoid using copper-based treatments in a tank with invertebrate, as it can harm them. Always follow the recommended guidelines for medication use in marine aquariums.

Calappa Crabs are commonly referred to as Box Crabs. They are collected relatively infrequently compared to more commonly harvested crustaceans like crabs and lobsters. The coloration of Box Crabs can vary depending on each species, but they often have mottled patterns and may blend in with their surroundings. Colors can include various shades of brown, yellow, or reddish-brown. They can grow to up to 6".
