Don't feel bad for your koi. I have always had both and they have usually lived together. My fantails have always been safer in the pond with the big koi. My koi have always been very gentle and have not bothered the fancys.
Nancy, thank you...but I meant I feel disloyal I have the goldfish in 300 gal tubs and now the fancy's are becoming my favorites. I still love my koi, but these
little guys have stolen my heart.
