That's an interesting tid bit. Seems like it would work well.One of the best tricks I learned for CBB fish is using a feeding station which is nothing more than a 3" piece of 1/2" pvc pipe with caps on both ends. Drill 6-7 quarter inch holes in the pvc reem the holes smooth. Take one of the caps ends off fill with frozen mysis or any good quality frozen food blends Rod's etc. Replace the cap put the feeder back in the water some place easily seen by the fish. CBB have evolved to use that long nose to reach into crevices and this feeder station mimics this behavior. There are u tube videos on this

I would never expect a CBB to eat flakes or pellets, like Paul said he had 1 out of 50 that would touch flakes.
If you need to get a CBB to eat Live Black Worms without a doubt is your #1 go to. They might be a bit harder to find in some areas but if your CBB is going to eat anything that is with out question your best bet. Black worms are also good to entice other fish as well, just for the record. My CBB in my home tank is a glutton and is far from shy about eating. He even tries to steal food from my porcupine puffer whom I hand feed once or twice a day in my reef tank.
With any fish it's about acclimating the fish to captivity and to eating in captivity and eating usually some type of non-live food. Getting the fish eating at all is your first hurdle and the hardest hurdle. Once you have a fish eating something, really anything you are already winning the game. Once the fish gets used to eating in a small captive glass box you can further wean them onto other foods such as mysis and chopped frozen sea food, but getting the to initially eat and eat well is the hardest part.
