My new pond is meant to be about water lilies and other plants, not so much about fish. (Mostly because of the heartache when the fish get eaten by predators, which happened with my last pond, but also the increased work to keep the pond clean with a healthy fish population.) I do want a few fish to eat mosquito larvae and also to look pretty, but I'm really wary because I don't want them to reproduce. I know it's hard to tell if goldfish are male or female, and I know some species can interbreed. Can anyone suggest a way to get a single gender population of 2-4 fish? Or several fish that can't breed? I'm willing to jump through a few hoops to make this happen....
Thanks in advance!
