My Aunt has a large inground pond with 3 large koi. Last year my Aunt saw some very little orange fish in the pond. We believe they were baby koi. The only other fish in the pond are a type of minnow. The minnows have a silver body with orange or red fins. So they weren't minnows. They didn't make it through the winter so I was wondering how would I go about catching any future baby koi if we see anymore. If we manage to catch a few I plan on using an extra tank I have as a grow out tank. As far as I know there aren't any baby koi as of yet. I'm just curious to know how we'd be able to catch them.
