Here are the types of aquariums that are suitable for hermit crabs:
* Glass or plastic tanks: These are the most common types of tanks for hermit crabs. They come in a variety of sizes, so you can choose one that is appropriate for the number of crabs you have.
* Terrariums: These are similar to aquariums but are usually made of glass or plastic and have a lid. They are a good option for hermit crabs that need a more humid environment.
Regardless of the type of aquarium, it should be large enough for your crabs to move around freely and have plenty of space to explore. It should also be well-ventilated and have a secure lid to prevent your crabs from escaping.
