Essentials For A Hermit Crab

Provide new shells for crabs to grow into. To maintain adequate body moisture, hermit crabs need larger shells as they grow. For a proper fit, the new shell should be one-third larger than the present shell and the shell opening should be the same size as the crab's large pincher.
Not all shells are suitable for crab homes. To ensure that tree crabs function in their homes, shells should be properly cleaned, processed and chosen by a knowledgeable hermit crab distributor like Jack's Aquarium & Pets.
Bathe crabs twice a week. For cleanliness, improved respiration and extra body moisture, bathe crabs by submerging them in lukewarm water. After several dunks, allow them to air dry.
Create a social, healthy environment. Crabs thrive on companionship. They are most active and entertaining when they coexist in pairs or in a tree crab community. They also need a warm and humid environment, 70°-85° F.
Promote exercise by creating a playground. Crabs love to climb! Coral and choya wood will encourage a lot of activity.
Serve a balanced diet and fresh water in shell dishes daily. Crabs need the calcium obtained from shell dishes. They thrive on premixed hermit crab food, along with a variety of fruits, vegetables, and nuts. They will bury their food, so make sure you remove all uneaten food prior to their daily feeding.
