Sad to announce having my first fish casualty due to suspected predatory bird. I lost my "Snow White" premier Koi only after having it in the pond for 2 days. I'm afraid that bird will come back for more. I went and bought two ornamental decoy cranes. Hopefully that will be the last of it. I don't think i'll be switching the crane around on a daily basis to ward off the birds. What do you guys do to prevent your precious fish from getting eaten???
