The Dolabella Sea Hare, Dolabella auricularia, also known as the Wedge Sea Hare, is one of the best algae-eaters in the home aquarium. The Dolabella Sea Hare can clean an entire 125 gallon reef tank of all hair algae in about two weeks - they are quite the efficient janitors. They are rather sensitive to pH and salinity changes and can take a little while to fully acclimate to a new tank (they should be drip acclimated). Featuring a dulled grey color and soft spiky appendages, the Dolabella Sea Hare makes for an interesting invert.
They are slow moving and well camouflaged within the rocks of a reef tank. The Dolabella Sea Hare is reef safe and is a relatively risk-free addition to any tank as it is an incredibly beneficial algae-eater.
