Here’s to the last day of creepy, scary, ugly animals for a while.
But the Halloween Hermit Crab isn’t prized just for its looks. The crab is used to clean the aquarium by removing unsightly algae growing on the glass and eating bits of leftover food. But don’t let its seemingly helpful nature fool you; the crab has been known to attack other members of the aquarium and eat them for dinner.
Would you want one of these in your aquarium? Does anyone have one?
