Can Hermit Crabs Live in a Fish Tank?
Yes, hermit crabs can live in a fish tank, but there are a few things to consider before adding one to your aquarium. Hermit crabs are not true crabs, but rather are more closely related to lobsters and shrimp. They are scavengers and will eat just about anything, including fish food, algae, and detritus. In addition, hermit crabs are known to climb, so a lid is a must.
