Cecil, You and gallop are right, I really over stocked! I never heard that one about the short digestive tract, but it sure looks like you vividly refuted that proposition.

To dispel another notion, GC continue eating through out their lives no matter how old they get. I've heard it said that after they reach a certain age they don't eat any more. Nonsense! My GC are 20 years old. You should see them pulling weeds along the shore when the water is high after a storm. They even start plucking off the leaves of willow trees that happened to touch the water. This year I planted a large water lilly, one of their least favorite foods. After ignoring it for two weeks they finally ran out of other grub and ate it up in a few bites.
