Last spring, I bought a TON of anacharis. It flourished, filling up the
bottom of the 15' x 30' x 4' pond. When the ice finally left, the anacharis
was gone! I'm assuming that my fish had a nice winter long snack! The
pond is understocked with fish. I have goldfish and a 4 or 5 smallish Koi.
Anyone have methods of protecting anacharis from the fish in winter?

Thanks!
