I use this site for plants - and of course they say it won't survive submerged. I had some luck with mine by keeping it in its' original pot and placing the rim at the level of gravel - then i would just remove dead roots. Personaly i would try it and keep a close eye - if leaves start to fade or yellow or start to turn translucent, or new leaves look unhealthy or the roots start rotting i would take out and place around the house. That is what i had to do for mine eventually.
Some people won't touch pet smart or any non
LFS plants because of mislabeling or snails, etc. For what it is worth, since even most LFS's and pet shops get their plants from common suppliers - it usually falls to the suppliers to label and they get theirs from aqautic nurseries - who ship in truck loads. Since even most LFS's don't have people who have plant knowledge or just the basics - it is hit or miss. I created for myself - a aqautic plant guide which of course you can always buy on the net - and i took it with me to my LFS's when i went shopping for plants - especially uncommon ones.
