They eat phytoplankton and/or zooplankton. The same thing that bait fish eat.
I spend quite a bit of time on, and below Guntersville. I have never seen one. We do have Bighead carp and have for a long time. Very close cousin the "Asian" Silver Carp. It is entirely possible that a bowfisherman took them to the Chick. They didn't have to swim there. There's no way to keep them out of Guntersville now, unless they can find the pod on Chick and kill them all. The guvment might come up with something to keep them from swimming upstream, but they'll wash downstream.
If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
