You might be better with gudgeon.

Green tench, too.
And you can buy them.

Mind, neither green tench nor gudgeon are what you might call highly
visible fish. They grub along on the bottom. We see our tench in the
form of an almighty splash if we approach the pond quietly, and in
summer they can be seen lying quietly under the water lily pads. The
gudgeon I see only by torchlight at night, provided the pond is fairly
clear of weed. And newts like a pond which is thick with weed.

I'm still glad we have the fish. Two of each, big placid things about 8
inches long.

Newts and frogs are far more entertainment value.
Damsel flies too are nice. And remember there are several species of
snails - I have a big whelk shaped one, the flat ramshorn type, and the
patterned nerite type.
