Is there such a thing as a snake trap to catch them alive? I would be doing that but I'm glad I don't need to worry about it. He looks like he could eat a bunch of fish. Can you just put a dish of sardines out for him each day
Fish, frogs etc all know there are predators out there, the strong will survive.............. Walking around I did see plop plop here and there even tiny frogs heading into the ponds. Just no toads, so strange usually a whole lot of them dropping eggs. Can see them at night having a party, not this year, unless our up and down temps have them on slow down. I have seen zero eggs from any frogs.
That's really nice to have a water snake around. Great photos of it too.
The only snake I've seen in my garden is a small terrestrial specias known as a sharp-tailed snake. They are mostly subterranean or nocturnal so I only find one if I'm lifting rocks or pots. Supposedly, they specialize in eating snails and slugs, so that's another bonus.
Right now it gets to stay, I do like nature, there are hiding spots for the fish. On a wait and see right now. i saw a brown water snake years ago, this may be the same one, but I have not spotted till now.
