These are the Aplysia sp. type. Very big about 4-5 inches long and at least 3 inches across. Harry and Larry have completely cleaned my whole tank of hair algae and are ready for their next big job. All I ask is that they go to a larger size tank with a lot of algae and that when they've finished their task they are payed forward to the next reefer that needs them. Here's a link to them. No pics. Pick up from me in Torrance.
