This year for some reason I have hundreds of little black fry. At first I thought they were baby koi. I saw a few that were pink but they are gone probably eaten. I thought the others would start to turn colorfull as they grew but the are getting bigger like an inch or 2 but they are still black. I don't know where the came from. Its possible they might be from one of the feeder gold fish I put in the pond years ago to see if they would live. Or are they Koi? I don't know help
