You are viewing the underwater camera in our outdoor Koi fry stock tank. These fish were laid as eggs on June 3, 2016 in our pond. We pulled as many eggs as we could find and raised them in a 50 gallon tub. When they were big enough they moved to their new home.The tank is 8ft across and holds approximately 625 gallons of water. Don't mind the debris floating around, the water is being filtered at around 2000 gallons per hour, the fish are very happy. The surface is roughly 1/3 covered with floating aquatic plants with long roots, you may occasionally see some roots in the shot depending on the camera angle.
