In my last pond (different property) I had bunches of toads every year. Here all I have seen are leopard frogs. They get quite large, maybe not quite as big as a bull frog, but maybe (?) I have bunches of these eggs now in my goldfish pond, should I leave them or should I net them out before it's too late? I am worried that they will use a lot of oxygen or dirty up the water or will they make my gf sick if they eat them? Do they eat them? I don't think they ate the toad eggs, but I have never had frog eggs before.

My understanding is that leopard frogs are pretty well-behaved and their tadpoles mostly eat algae. I would leave them alone, but I'd defer to anyone else who has better experience with this particular type and/or in your area.

well we got a cold spell and the eggs seem to have not liked that. They turned a milky color (like moldy?) and I ended up netting out most of them.

Late to the party here, for future reference and my own experience with Leopard Frogs, (we have them a lot here) the ones who occupy most of my yard. I have never had an "infestation" or over population of Leopard Frogs in all the time I have had the ponds. I'm not sure where they go? Occasionally the adults will eat my baby gold fish. But pretty much they stay to themselves. Goldfish do eat the tadpoles. I never see more than 3-4 in the ponds at once. IDK how many more there might be underwater, but as I say, they aren't a problem. I clean out leaves and debris regularly with a rake. I am sure I will grab a frog egg or three when that happens. IDK what they do? Maybe they are helpful in the ponds ecosystem? I just leave them be. Only the strong survive.

When I had a small pond, I often got frog and/or salamander egg sacs. I just let them be. They usually hatched out to pollywogs and through natural attrition (birds, perhaps the goldfish, small mammals, my cats...) I never had any issue with too many growing all the way to frogs. Some likely did, then hopped away. I still get tons of 'peepers' in my pondless water feature and assume there may be egg sacs in the water reservoir that I just can't see. Let nature take its course is my advice.

Even thought I netted out many that seemed to have died, there were still many that hatched, hundreds. I think most of them have been eaten by ? Because I don't see too many at one time anyway. I have probably 4-5 adults that stay around my pond all the time. And a garter snake
