Hi NU,
I think it is Euastrum oblongum, rather often to be seen in moors.

Very interesting algae. I still have yet to find any in my tank. I do see green things occasionally, but they have a mean looking red eye on them. I also have some Duck Weed growing on the surface, and it is even growing new leaves, but that doesn't count. Too big to look at.

Thanks for the ID, Ernst. From a local clear-water lake outlet.

Thanks John & Mitch.

Mitch, have a look at the underside of your duckweed both the leaf and roots. Or, brush off the debris and stuff from the underside onto a slide; there should be some 'goodies' there.

Ah, I will check that. I was in there this morning already, checking on the snail eggs, and saw that the Duckweed is multiplying quite fast. Maybe I should document that with my Macro lens.
