I went to Petsmart but they didn't have any Fanwort (or cabomba, as aokashi corrects me all the time. haha) But they didn't have any!! Petsmart calls it a "frill plant", btw... I forgot that I usually go on Wednesdays and that's when they get their shipments in. But they did have water wisteria and I did need another plant for my girls side of the divided tank, so I got some of that and I love it! It looks so nice in my tank! I'm going to go back today and get a few more bunches so I can line the back wall so Fishie stops flaring and I can put more in Jasper's side because she has been stressed since I took out her "Aqua Fern" that I got from Petco that turns out not even to be aquatic! And also get some Cabomba/Fanwort/Frill plant. All my hornwort survived my last AQ salt treatment (and is over a foot long now), but all my fanwort turned into bare stalks.
The point of my post was to say that the water wisteria did fine in the bag and I even left it in my car for 2 hours- it was warmer outside than I thought, over 50 degrees- and it was totally fine.
