From what I heard & saw at Jack & Wendel's (Ocean Aquatics), you'll need two or three running cultures of rotifers to keep them fed & alive. It's time-consuming, which is why they're getting out of the clownfish breeding biz. I have several gallons of rotifers, but I don't know if its worth it to you to ship some (probably $$$ for shipping). See if there are any local cultures that you can get a hold of. I feed rotifers to my corals, clams & stuff & they love it
By the way, I got my starter culture from OA.
