Hermit Crabs are always looking for new "homes" they can grow into and they often resort to cannibalism to acquire them. If new homes are available, crab and snail fatalities in your aquarium can be greatly reduced. It also allows your crabs to grow faster making them better cleaners in the process! Not to mention the shells add color to your tank...
Size 1"-2" Priced Each
Measure Shell Openings. It is important to choose shells with the correct opening size for your hermit crabs. The opening size you choose should be 1/8" bigger than your hermit crab's big claw. You should measure the length of the largest claw, not how wide it is
Love the natural looking colors of the shells. In the first two nights 3 of my hermit crabs moved in.
