Hi, I purchased a "sword plant" from petsmart but I now read alot of
plants pets store sold are not really meant to be submerged, I figure
either it is amazon or brazilian sword, is there a way to tell whether
I have a true aquatic or not? I have searched through pictures on
internet but I am still not sure how to tell what my plant is.

If I take a picture will you guys be able to tell?
