hermit crab aquarium
aquariums or other plastic or glass habitatas can be used to house hermit crabs. a good rule of thumb is 5 gallons for every 2 hermit crabs.hermit crabs are social and do best in groups. place half a coconut shell inside the habitat so they can hide inside and use 2-3" of either aquarium gravel or coconut fiber which is sold at pet stores. be sure to include sticks, plants and other decorations so they can hide and have fun!
