Seahares are notoriously difficult to get to feed on other types of food. I have tried all sorts without any success. This may sound stupid but i actually cultivate hair algae for my Seahare. In one of my tanks I have placed a pond basket at surface of water which is very close to the light, within days I had hair algae growing on it. I have no phosphate readings and no nitrates in this tank yet it still grows, I let the algae grow for a few days and place it in the tank with seahare. He will find the food itself no probs. Another basket is placed in tank to start growing algae again.
My friends think I am nuts, I am the only reefer who wants hair algae.
