Ok, got home from school and fed the tank this morning, and just now. He barely ate but maybe 1 or 2 frozen mysis this morning, but when I fed just a few minutes ago, I mixed it with some flake food, and while the other fish ate both, he went crazy on mysis. I'm not sure how much they usually are supposed to eat, but he ate about 10 - 20 mysis. I haven't seen the YT go after him much, but when he does, the CBB turns on his side and pokes him with his spines that he has. I think things are a lot better, and are still improving, so hopefully no fish will be taken out of the tank, but if I end up having to, the YT is moving out!
