Does anyone know of somewhere around Ohio that I can buy tilapia?
I want to try stocking them for algae control once my water is warm enough.

As you may have noticed they are not commmonly used or available around here.

Ryan Freeze down by Cincinnati runs Tilapia; perhaps he can remind us where he got his.

How big a pond do you want to stock/how many do you need? If a small quantity, the pet store route might be possible and maybe not too costly.
