Thank you so much desertanimal, really appreciate it.
Interestingly, even though it's only been a week or 2, the rescue in glass seems to be doing the best with absolutely no fungus and her roots are turning the most green. We'll see how it goes. I'll have to be sure to flush well, maybe weekly, and dump the water afterwards.
So far they are all looking a lot better than when they arrived. I hope to be able to post happy pictures of them in a few months!
