You will receive blue leg hermit crabs and we are currently are also finding some green metallic legged hermits along with the blue legs which are doing the same grazing as the traditional blue legs. You may find a few mixed in with your order. If you want only traditional blue leg hermit crabs please let us know.
They are very active and will aggressively attack most hair algae and other fleshy algae that live in your tank. These combined with sally lightfoot crabs, Emerald crabs, and astrea snails will keep your algae under control. Blue legs are very easy to care for and will eat anything presented to them. They will not attack other invertebrates but is something dies; they will dispose of anything that remains. We will send the blue leg hermit crabs wrapped in a damp paper towel for overnight shipping. Blue leg hermit crabs shipped via Priority Mail will be shipped in water.
