I was reading a fascinating article in Reef Hobbyist Magazine. It was how he figured out a good way to feed copperband butterflyfish because when they normally eat, it is more difficult than other fish. They are very precise. Normally, they will end up looking thin because they don't eat enough. This is the new approach: Take a small pvc pipe and drill small holes into it, just big enough for the fish's beak. Cap and glue one end of the pipe. Also, I forgot to mention this, don't put a ton of holes because you don't want a lot of food floating around your tank. Now, all you have to do is fill it up with mysis or whatever you prefer to feed it, and cap the other end tightly. Put it in the tank and your fish will be looking good in a matter of time. If you want to spice up the feeding mechanism, put a suction cup on the end and you can hang it to the side of your tank. You could also use this for other fish with long beaks, like yellow tangs.
