My female goldfish (3) are nine yrs old. I should have left well enough alone, but since I lost 2 of the other 9yr olds this winter , I decided to add 3 small ones a couple of months ago. My old fish never had babies, which was fine, so I guess they were all the same sex. Now I’m regretting adding new fish since I may end up with babies overrunning my pond. My pond is 10’ by 12’ and 2 1/2 ft deep in the center. Can the 9 yr olds still produce eggs and spawn? Also, what’s the best way to catch the 3 small, new ones before they spawn? Prefer to not drain pond but if that’s what it takes, I will
