Pond advice needed
Hello all - bit of info required please. I have a garden pond which I dug out and lined myself using a lining sheet with an old piece of carpet laid below it to prevent any tearing. I did this last autumn. I have also placed a couple of largish twigs (small branches really) as an escape route for amphibians and small mammals.
So far so good - this year I had a few dozen tadpoles in the pond which were quite well advanced - rear legs starting to show signs of development. I also had two newts in the pond, one of which was brown and showed no interest in the tadpoles whilst the other was almost black and seemed to find the smaller tads a tasty meal. Then I went away for a week and came back to find no sign of any newts or tadpoles in the pond. There was however a much, much, larger frog in residence.
Now to my question. Are adult frogs as cannibalistic as tadpoles? Would you have thought that in the space of the week I was away the tadpoles had advanced to the point of leaving the pond, or would the adult frog have devoured them? I also seem to recall another thread on here mentioning that fish will also eat frogspawn. Is this true of all fish, or would it be safe to introduce 3 and 10 spine sticklebacks?
Thanks in advance.
