The few CC I have left are very slow to come up the last several times I have fed, and I am well south of "Snrub". I have been feeding less and only on the warmer afternoons. We cleaned and ate six of the larger BG a couple of weeks ago, and they were still full of undigested pellets from the day before, so I slowed way down on the quantity and frequency of feeding. The water has become very clear in the older pond, and I can sometimes see a CC swimming very very slowly on the bottom, not even stirring up silt.
