Pond Boss Forums INTRO Questions & Observations Looking for source for CNBG in South MO

So i picked up 500 CNBG, 6 more grass carp and 10lb of Flathead minnows. Hour drive to pond and they all made it, not one floater.

Now, i was assured these are CNBG. I can't tell at this size. They're like 2 maybe 2.5" He said they're bluer at this size is one way. For those familiar with this size CNBG whatcha think?
