I got two sea hare's from Live Aquaria to help combat my hair algae problem (along with water changes, lowering light time and adding phosphate remover). But its been about a week and they have barely touched the stuff. I see them slither over it, but they aren't eating it.
Did I get the wrong species of sea hare for eating hair algae?
I bought two of these for my 50 gallon tank:
