I got 3 bullfrog tadpoles. They vanished. So I got 3 bigger bullfrog tadpoles. They vanished, too. These tadpoles were very large, almost as big as the fish (which have since grown a lot). One day, I found two tadpoles in the skimmer and returned them to the pond, but that was about three weeks ago. There has been no sign of any tadpoles since then, and I put a total of 6 into the pond starting in March.
Any idea what could have happened to them? I'd like to have frogs, but I'm not going down the tadpole road again. About a week ago, I startled a fox who came up our driveway; it startled me, too. I've seen an owl by the pond at night twice, but not in a couple of months. During the winter a big hawk used to sit at the edge of the pond, but I haven't seen it in the immediate vicinity of the pond in at least two months. I understand not seeing the predators does not mean they haven't been about, but I don't think my pond is easily accessible to foxes or birds who are not herons. Could the fish have eaten the tadpoles? I wouldn't have thought it likely given they'd be eating something almost their size. Or could it be that the tadpoles are just really good at hiding, all the time?
