I'm in need of loads of rain water as my grass seeds are complaining about the sun... So that's when I checked out an old, very dirty rain water barrel in my garden.
That's when I saw some creature swimming in it. About 1 cm length, I've drawn it. It was a bit fuzzy around the edges. It swam with its tail. It was a living creature, aware of its surroundings. When I blew on the water (it was close to the surface), it stopped swimming.
Any idea what this is?
I left that water barrel alone.
