I cleaned up the nice balcony #medaka pond enough to move there the medaka that were in the nasty garden medaka ponds (as well as the big water lilly).

Now, I wonder if I did the right thing. All the medaka in the balcony pond died last winter (No idea why, the snails survived, and I even spotted a shrimp - I thought shrimps were not supposed to live through the winter), whereas at least five, maybe more (the water is nasty) survived in the garden ponds. 🤔
