If it's any conselation, Kirk, my role model CBB isn't ravenous, either, and he's fat. He eats well, but looks like a sluggard with the only other fish in the tank being a 2" baby sailfin tang and 4 lyretail anthias. My typical feeding routine is to stick a frozen cube of mysis onto the intake grate of the powerheads and let them do the work. As soon as the cube hits the water, the anthias start their piranha-esque flurry, and the sailfin and CBB start getting a little excited. As the chunks of mysis begin shooting out of the powerhead, the anthias are faster than the flow, and attack very aggressively, often grabbing mysis before they're even 12" out of the Seio 2600 powerhead. When the bulk of the mysis finally clouds out into the water, the CBB typically only gets about a dozen or so pieces of the mysis, and the sailfin about doubles that. The anthias are usually done eating long before the food is gone. They're such small portion eaters, and such high energy, no wonder they require 3 feedings per day.
With the 2 or 3 feedings per day, the CBB gets a decent portion over all, though. But in this crowd, he always looks like he's just pecking at left overs at feeding time.
