This was my method for training my Copperbands to eat.

I have since sold one of them, as I couldn't get them to play nice. But have had the bigger one now for over 9 months and he is doing great. I am really impressed how he adapted to my bully Yellow Tang and my bulldog Cinnamon Clown. Both still occasionally take a lunge at him, but he artfully dodges them, and resumes doing his thing, without fear (was certainly not the case when first introduced to the display tank).
Only problem, is that he still won't eat my aiptasia, which is why I originally got him. I am probably feeding him too well... He does go around picking at live rock, though, so must be finding something there to his liking.
