I have a very fat and happy Achilles I received through Dr. Reef 2 weeks ago. He's very active and picks at rocks/algae all day, but so far all he's eating from me is nori. I have a yellow, sailfin, and hippo tang as well, and they all go crazy for the frozen I put in 2x daily. He's the biggest fish by far and the yellow made a slight attempt to punk him after he was added, but was quickly put in place. My understanding is they basically eat all algae in the wild, so I just want to make sure he's not going to be missing out on anything if he just sticks to the nori.
