I was planning on putting them in water on Friday, but jumped the gun a bit and did it tonight. I dunked all 4 sets of eggs I had, collected on 8/28, 8/29, 8/30, and 9/1. So 9, 8, 7, and 5 days incubation respectively. I noted the number of viable eggs in each, so we'll see when/how many hatch out, but it'll probably be anywhere from a day to never lol. The infertile eggs did fungus up a bit, but it didn't seem to spread to the good eggs.
The 8/28 collection I just put on a paper towel. All others I cut an empty tea bag (the kind you fill up with loose tea) into ~3x3 inch squares and put that on top of the paper towel. There's a rougher side to the tea bag which made transferring the eggs from my fingers to the tea bag easier, and it lifted off the paper towel easily with all the eggs when I transferred them to water. So I'll likely do that or something like it going forward.
