Transferring fish from another pond or lake can bring other invasive species other than fish related nasties. Google Starry Stonewort Nitellopsis obtusa. That is in some lakes and can be transported in what looks like to be clean water........
Virtually impossible to get rid of once it's in the pond. Maybe a complete drain, excavate and refill. but I'm not sure.
