i live by a store called the coastal aquarium. they make me so mad. here are some of the things they do wrong: . not enough sand . they never change thier sand . not enough food . no water . no knowladge of hermit crabs . no shells to change into . nothing to hide in . they keep them in a small cage that doesnt keep humidity in thats only some of ythe things they do wrong. i have gone in there and found the hermit crabs eating thier own poop because they have no food. also they charge 2 dollars more for hermit crabs with painted shells.
