I've been feeding this to my Koi for over 15+ years. The pellets in my last 10 lb bag, ordered through Amazon in October, looked unrecognizable to the pellets I've fed before. They were slightly smaller, darker, more dense but they still floated, and they had an off putting smell. The difference was so pronounced I thought the food might have been counterfeit. I looked closely at the packaging but it looked the same.

The fish are eating it FWIW.

Did Sho Koi change their formula? Has anyone experienced anything like this before?

TIA
