I've got a Copperband butterfly that eats out of my hand. He used to be a very skittish little guy, he's now a giant and when he sees me, he races to the front of the tank wanting me to feed him. His favorite is clams on a half shell, I used to just put one in the tank and leave, but i eventually became annoyed with the tangs aggressive eating behavior and decided to try and get my CBB to eat out of my hand and ever since, he's been eating out of my hand.
I've also had a Moorish Idol that used to eat out of my hands, relatively close to when my CBB began, but i was forced to get rid of the idol unfortunately, after he acquired a taste for all my expensive brains corals... Was definitely a bit devastating having to rehome him after having him thriving in the reef tank without any previous issues...
