Do hermit crabs like peanut butter?

Hermit crabs enjoy exercising on plastic wheels like the ones given to rodents! Also, they love to climb, so providing lots of safe wood, plastic aquarium decorations, or plants gives them places up high to explore. A good hermit crab toy can be plastic plants, the shells you provide them to wear, or a "moss pit" which is basically a moist moss play area for them. Hermit Crabs love to dig so make sure the substrate (ground) inside the tank is sand or coconut fiber (not gravel or tiny rocks because that can retain water and hurt the crab when they try to dig under a rock/toy) Be sure all toys are clean and safe (boil them in water and let them air dry)
