Some aquarists love them as pets and others consider them nothing but pests. Some of them are very beautiful, but they all have "jaws of steel", able to inflict a serious wound or kill almost anything in your tank. This article takes a look at both sides and lets you decide.

Imagine hiring a service for just a few dollars that not only cleans your tank 24/7, but also helps to keep your nitrate and phosphate levels in check. Sound too good to be true? It's not. Reef Safe Hermit Crabs do all that and more. If you want to keep your aquarium glass and Live Rock free of algae, a few of the Reef Safe Rock & Glass Cleaners will get the job done for you.

This not only removes unwanted nitrate producing substances, it also stirs and aerates the sand (very important for Deep Sand Beds), releasing toxic gases.
