After feeding the fish, I was walking along pond side and spotted something tiny swimming beneath the green waters. My first thought was, I don't have any fish that small, but now I do. Two little fish, about 1 1/2 inch are kinda living all to themselves along the side of pond where I have a lot of pots of bog plants and a big bog planter with hiding places under and behind it. I didn't think my fish were old enough to spawn, wrong again. They were probably 5-6 inch some 6-7 inch last spring. Much bigger now. I guess since they have figured out how to survive this long, maybe best to leave them in the pond to grow as big as possible before winter. Do the koi eat the babies if they find them, I know I have frogs that will if they get to them. They are Koi babies, but not anything exotic.
