Hello my name is Aelin and me and my family recently started a fish pond it's been running about 3 weeks and 2 days ago we were able to aquire 3 buatifle young koi fish. A month ago we went to a supplier who sells koi fish and it is run out of georgia. Her store name is the koi store. She said that she would put no more than 15 fish in our size of pond. We decided to get a few just to make sure they would survive before investing a lot of money in fish. She said that in late April she would be getting a new shipment of fish and we decided we wanted to get our bulk of fish their. Our new Pond is about 6 x 5 and 3 foot deep. We then have a shelf going around the edge of the pond going down about a foot or so. We got a smart pond, pond filter and a big waterfall running into the water.
