Well, Petsmart only had one type of real aquatic plant in stock when I went in the other day. (Why do they sell bamboo as aquatic..?)
Anyway, it is called Anacharis, here is a pic I got from the internet:
Nothing fancy at all, but it's better than nothing. The other pet store in my area told me someone had bought all their plants and wouldn't get more in until Thursday. So, this was all I could get.
I hope to find some of those moss balls sometime in the future, they look neat. :)
