Unsure if plant is aquatic or not...grrr

There are several plants in my aquarium that I know aren't aquatic. They haven't died on me yet, and will be replaced with something actually aquatic once they start looking poorly.

I have a sword plant however which I'm just not sure about. Some sources say it's not aquatic, some sources say it is...and it's doing rather well (compared to the other ones). I had to split it today to give some of the newer leaves a bit more growth room and light...the original 3-4 plants has become more like 5 or 6 and the roots had spread a good 6 inches under the substrate. Granted the growth isn't explosive or anything...no CO2, ferts, and an undetermined amount of wattage because I moved some sort of compact fluorescent floor lamp over part of the tank which isn't marked for wattage.

Just thought I'd ask here before I drove half an hour just to check the label on a plant...
Has anyone had similar successful growth of a non-aquatic?

heh...was trying to avoid showing off my horrid aquascaping but anyway...

This is about as close as I can get...there is a mild current in the tank so everything blurs when I try to take a more macro shot...

Darn lazy Ottos have not been doing their job obviously!!!

And full tank shot before I split the plants up a bit...

I know the ones to the side and back aren't aquatic...

I suspect you had several plantlets started in the same pot as swords generally propogate via runners

Thanks for the info. ^_^ I prob. shouldn't have said "splitting" as it really was much more of an "untangling". The heavy root feeding thing also makes sense considering the pretty impressive root growth they had. I have experience with terrestrial plants since I've worked in a greenhouse before, but my aquatic plant exposure has been a bit limited.

I'm looking into replacing our hood, and rigging up some DIY CO2 in the future so as they get a bit bigger I'll attempt to move them farther back if they do start getting large.

Honestly I have no idea...it wasn't purchased by me, and it was a few months ago. I was just heavily suspicious because it came from a chain store that has a tendency to sell non-aquatics.
