Thanks and welcome to GPF! There are 10 Koi and the rest are goldfish. The pond is about 3000 gallons including my bog. The Koi were all in the range of 4-6 inches when I bought them but now some are in the 18-22” range. The center of my pond is 42 inches. I keep some water moving all winter. Usually I just keep my waterfall going but I have an air pump too. Last winter I turned off my bog pump for the winter because we were gone and I wanted fewer pumps to worry about. I recommend to stay with goldfish as long as possible before thinking about getting Koi because it’s so much work with larger fish and so many things can go wrong!Wow--your fish are huge! And so many of them. I am just learning about fish and only have 3 shebunkins which I think have gotten big (about 7" long) compared to what they started out as ( less than 1" ) when I bought them 2.5 years ago. Now I look at your fish, which I assume are koi, and am amazed. I see that you live in Chicago which I know gets really cold in the winter. Do you need to do anything special to help them survive the winter months? I'm in Vancouver which stays pretty mild so I haven't needed to do anything different for the fish. I'm guessing they hibernate.
