That plant looks like the plastic water lily plant that I have. It used to be in Dagger's tank and was a favorite of mine until I found him caught in it one day and promptly removed it. I still have it, hoping I can still use it again someday. Here's a link to it:
I have added a few new plants and had an issue with one female (Gender Bender) So I got a new female and she is wonderful. I had so many issues getting this tank set up, but I was successful! So the pictures you see with a bunch of plants in the back ground are the newer ones.
