The plant on the left is non-aquatic. Will die soon if kept under water. Scientific name is Hemigraphis exotica, not sure what it is call in pet store.
It's called purple waffle. Not an aquatic plant. It's almost a bog plant tho... I just got some this past week at a LFS in Reno because my wife thought it was pretty. I didn't Google it on the spot, like I usually do, because we were in a hurry. After we got home and I planted all my new plants in the aquarium I did some research and found out its purely terrestrial but likes to be in very wet soil. Lol we both got duped.
