Hi Peter,
Thanks for your message.
I now slowly get the impression that the dark period after may end …
Let’s hope so. There are a few of us now trying to do our bit with Paro’s, time will tell if we can be successful.
on the yeast method: Nevertheless I am cautious because I don’t want to infer yeast into my Paro-tanks …
Me neither, its one of the reasons I stopped using yeast in my paramecium cultures.
on the visibility of young fry: After free swimming young Paro-fry are mostly not visible at all, but about one to three weeks later one sees more and more. Of course, some parents are aggressive against their young, but not all. One has to try it out. The youngest often hide in leaves on the ground, later on in swimming plants on the surface.
So far I have seen only one fry (the photo I posted), hopefully there are more that are hiding.
on the name: It’s filamentosus (not -um, at least in the original description).
Thanks for pointing that out. I have changed reference to that on any of my posts where I can.
