He is eating again today - in fact, I was surprised, as he's typically voracious, but yesterday stayed in a corner swimming forward and back looking very much like any other animal in pain without eating any of his faves. I blended the frozen food for the others with some raw garlic so it would at least be in the water. (Yes, I could be attributing more feelings to him, but he's a pretty cool fish.) Today's feeding spawned an all out feeding frenzy and Tang participated!! He's really diggin' the Nori soaked in garlic... and is swimming the whole tank again. Just... really nasty open side. I just can't imagine that he can cover this whole wound. :'(
