DIY Hermit Crab Habitat
Use plastic containers to make a habitat for your hermit crabs! Remove the lid from a plastic storage bin and pour six inches of sand in one side and soil in the other side. Hang plastic baskets on the walls with zip ties, use suction cups to hang pieces of a net around the walls for your crabs to climb, and consider attaching a hamster wheel to the wall of the cage for your crab to exercise. Put some rocks or seashells in small plastic containers for your crabs to use to climb out of the containers, bury the base of the containers in the substrate to make pools, and fill one pool with dechlorinated fresh water and the other with saltwater. Make a natural hide by cutting a hole out of the side of a plastic bowl, painting the bowl with glue, and rolling the bowl in sand or coconut fiber. Regularly moisten the soil, fill the baskets with seashells for your crab to change into or a moss garden for humidity, and add plants and other decorations your crab can climb. Place a thermometer in the cage to monitor the temperature for your pets and a hygrometer to measure the humidity.
