Yeah, I now feed a chunk and kinda keep it pinched with my thumb and middle finger in towards my palm so they have to swim into my hand, and i've started moving my hand around while doing that so they don't get scared when my hand is moving in the tank, it is kinda freaky though when you got the ol' rabbitfish in your hand...i think the funniest thing is just watching everything go nuts, hermit crabs leaping off the rocks, sally snatching everything up in site, corals snatching up chunks of food, shrimps climbing on you for more....they are greedy! lol
As far as feeding, some people hold a chunk in the water and let the powerheads blow the food around, or you can let it sit in some water and use a baster.
Aiko used to chew it up and feed with his mouth, but he got stung by a rabbitfish, so i would not recommend that.
