Eric, No, I added no more methylene blue, but when I combined it with Maroxy I would re-dose that at maybe half strength. This has been more than a while ago, but as I recall I used maybe 4X too much (I hate saying that! I'm not too sure... water was very dark). Water is still dark when they hatch; if it gets too light before the fry are swimming for a few days, I'll add a bit. The fungus was a trip... like white lava rolling over the egg plaque. Could cover the whole thing in a couple of hours! If there's not adequate dye left, it will attack seemingly healthy larvae, and appears dangerous until the fry have been up for several days. I've never seen it on the eggs of any other genus, and I've always been curious about what it might be... Nasty!
