Can only endorse what has been said already.
We have two ponds. A big pond with two fairly vigorous water features which houses our fish, and a very small one which was put aside for tads and/or newts. Guess where we find our newts in abundance?
That pond is
tiny, probably the smallest pre-formed you can buy at a garden centre, yet the newts love it. There's always babies, every year and they haven't got any fish to worry about.
"If it ain't broke don't fix it" is my motto, but someone always comes along with good intentions of making things
better.
A friend has added a (albeit very weak and small) water feature and cleared the newt pond of overgrowing vegetation so we "can see the newts better".
Yup. I am going to put it back the way it was as the newts seemed happier with the dark, heavily shaded by vegetation, non-moving water.
Watch and listen to what the wildlife tells you.
