Hi all, we have had our pond up and going since last march. Its around 3000 gallons. We have some beautiful koi in it but I put 4 comets in it (I wish i hadn't). We have had babie fry all summer long. I think most of them are comet fry but some look like koi. Comets are pretty but I just want koi in there. Now some of the ones I think are koi are small like around a 1/2 inch , how will they do through the winter. I am thinking bout taking the little ones out and bring them in my aquaium inside. Will that work?
