First and foremost, make sure your crabs have plenty of clean water. Use a nonmetallic container. An open shell makes an ideal water container because a certain amount of the calcium from the shell enters the water and is ingested by the crabs, which helps in their development. Feed land hermit crabs a commercial food formulated especially for them to ensure they receive adequate amounts of nutrients they would gain in their natural environment. A couple small pinches for one to two crabs every two to three days is sufficient.
Hermit crabs eat small amounts very slowly.
Any uneaten food should be removed after two to three days to prevent spoilage. Avoid giving them bread or meat. Because crabs are nocturnal, the best time to feed them is before you go to bed. As they get to know you, hermit crabs can learn to eat from your hand. Inc. All rights Reserved.
