I have 6 goldfish in my pond. 2 are new this year. We also added some minnows. The 4 from last year seem like they doubled in size under the ice this winter. Now I have babies. Dozens and dozens of babies. Will the larger goldfish eat them? Or is that only the eggs? I don’t think my pond could handle all these fish as they mature and am hoping nature steps in and they become snacks.
