My Lemonpeel is like a cow. He grazes on EVERYTHING! Lemonpeels are very curious and will nip at everything! I had mushrooms and ricordea. They are gone, except one mushroom that made his way under the rocks. It doesnt matter how much you feed him, it is natural for him to nip all day long. You can put as much macro-algae and seaweed in as you want, it will not help. However, I bought some hard coral frags, and he nipped at them once, and that was it. This is my experience with my peel.
