Hermit Crab Habitats
Pets are generally at their happiest when they are living in surroundings that closely resemble their natural habitat. For hermit crabs, this means access to sand that they can dig in, and salt water to bathe in. This can be achieved by taking a normal fish tank and kitting it out with various ornaments, and dishes for food and water. You can also purchase habitats that have been made specifically with hermit crabs in mind. They will need a dish for fresh water, and water treatments are available that prevent crabs being harmed by chemicals in tap water. They will also need a dish containing salt water for bathing, and another for their food.
It is important to remember that hermit crabs tend to come from habitats with a warm climate, so this should be replicated also. This can mean adding a heater during the colder months, but be sure that it is installed correctly so that the crabs do not come to any harm. You can purchase specially designed thermometers that will allow you to monitor the temperature of their habitat. Hermit crabs also like humid environments, so make sure their habitat has a lid to help keep the moisture in.
Although hermit crabs are social creatures, it is best not to keep too many in one habitat. They are active animals and need room to be able to walk around and investigate their surroundings. They also like overcoming obstacles and climbing, so make sure their habitat has plenty to keep them occupied.
