I like the stocking number of 20 CC to the acre too. They should grow fast and not harm the water quality for the primary focus.
6" CC got that big by eating feed as they are raised in high density depending on it where goal production is often > 40,000 to the acre. They'll eat feed but as Sunil suggested ... they may be reluctant to come to the surface for it at 6" TL. Most of the feed 6" CC fed on growing to that size was sinking crumble. But they will eat feed, if they won't come to the surface, you just have be sure it sinks.
Pretty sure I have seen some whiskers coming to the surface the last few evening while throwing feed out
But I don’t have video to support it and it’s been at sunset, 20’ off the shore so I’m not getting too excited yet
