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.
This is my second Dolabella. The first possibly died when there were no more algae to feed on. This one appears robust and moves all over the tank in search of algae. Can recommend this strange looking creature.
