You have fed them a lot, so they have good flesh. The water temperature should be between 24°C and 26°C, if you can raise it a bit more, so that the body shape is even better.Isn't it too early to measure the length of the KOI? We concentrate on feeding them until the end of September or mid-October. Oh? You have the KOI Show in the middle of summer, don't you? Excuse me...
