Hey Bad Boy,
I think you have a different situation. I have not found dead fish at all.... I hope it all turns out for you. I know I was freakin..... There is something spooky about 70 or more little fish at the surface of the water, whiskers up, ya know.
Husband thinks they are feeding on the top. He watched them this weekend. We also heard other fish at the banks splashing and feeding. So I think he is right about it.
Good luck to you.
