My first batch of CC that I stocked in late September 2015 started eating pellets well the second day after stocking and didn't quit until the water temp dropped into the upper 50's. The spring of '16, they started eating again, becoming more aggressive as the water warmed. By May it was a frenzy like in a hatchery pond. Today a school of my original CC came swarming around the feed about a foot under the surface, and I saw several skimming the top. I am throwing a couple of handfuls into the new pond feeding ring every afternoon, and so far only FHM coming up. The food sinks after a half hour or so...maybe the CC eat it then.
