I make cbb feeders. Works great. I have a few tangs and he's always able to eat at his own pace.... Though he's a pretty aggressive eater without it.
USA - Copperband Butterfly (CBB) feeder
Want to ween your CBB off of live food/clams, or, teach him to feed out of this so he's not out-competed in the tank during feeding time (*cough* tangs *cough*)? Then you need this in your life, so does your CBB, hah. The 'inside' ends sit one over the other which is where you place your yummy...
