The Benefits of Hermit Crabs in Your Aquarium

The hermit crab isn’t just another pretty shell – this invertebrate likes to clean up after itself, and the rest of its tank mates! Here’s why you should let a hermit crab move into your tank.

If you have ever gone on vacation to the beach, the chances are good that you are familiar with hermit crabs. But hermit crabs don’t just make great pets for kids, they can also make for a beneficial addition to your marine tank. These saltwater invertebrates could help to keep your saltwater tank clean and debris-free which means less maintenance for you!

What Benefits do Hermit Crabs Provide?

Hermit crabs make an excellent addition to any saltwater cleanup crew because they are natural scavengers. This means that they will sift through the substrate in your tank, feeding on bits of detritus that they find along the way. Things like uneaten fish food, algae, and decaying organic matter all become food for your hermit crabs.

They work even harder than algae-eating species of fish and because they feed on leftovers you don’t have to worry about too much supplemental feeding. As long as you supplement their diet occasionally with plant matter, crab pellets and pieces of fish or chicken, they will be just fine. As your hermit crabs dig around in your tank, they will also keep your substrate aerated which can be helpful for the beneficial bacteria living in your tank substrate.

Tips for Keeping Hermit Crabs at Home

Keeping hermit crabs in the marine tank is fairly easy because they have similar tank requirements to most saltwater fish species and they are generally hardy in regard to minor changes in tank parameters. The ideal pH range for hermit crabs is between 8.0 and 8.4 and they prefer a specific gravity between 1.021 and 1.028 with undetectable ammonia and nitrite levels with nitrate levels below 10 ppm. Your crab will also prefer a kH between 150 and 215 ppm.
