In spring time when the water temperature starts to get over 65F they will come into breeding condition. The males then chase the females around the plants at the surface of the water. In the excitement of the 'chase' the females release thousands of sticky ova (eggs) and the males release their milt (sperm) which fertilises them as they stick to the water plants.
