Desperately seeking Sea Hare's

[Kayleb]

I am looking for sea hare's, Been battling a menace green hair algae for about a year now. Only thing I've found that would touch it is sea hare's. I bought one a while back but it died within a week or two, Could have been from overindulgence, but I'm willing to try again possibly multiple if I can find em. I'm in Victoria area BC.
