at his size, I would not rely on algea in tank to sustain him. I would feed algea/ frozen at least twice a day. Not necessarily twice as much food into the tank. but less food, more often. Fatten him up. They are also more susceptible to ich, more reason to get him eating well and healthy asap. Do you broadcast feed frozen and nori on a clip?Yes for sure. He is really thin I noticed, which is part of why I took him, I have a thing for rescues! Ive got a baster to spot feed if I need too and tons of algae. They fed them at the store for me and he was up here competing with other tangs and angels for food that were way bigger than him! Here are some better pictures.
