Just saw something amazing.
From time to time, micro hermits climb over my weir and end up caught in the ball valve. I notice, as it blocks it partially, and the emergency overflow gets used, which is noisy.
This one must have had a particularly hydrodynamic shell as it didn't cause this. It must have been there days, because eventually it abandoned it's shell. I found a hermit walking around the glass of the sump like Spider-Man, without the weight of its shell it was very nimble.
I got it out, put it in a jug of water and got the camera ready. I then put a spare shell in and as expected it immediately ran to it, gave it a quick once over and reversed into it. Amazing to watch. Unfortunately idiot here didn't hit record.
so I can't share it with you, but it was very neat to see...
