Plant id before I put it inside the betta tank

[BettasRFriends]

I have no clue what the name of this plant is but it's been inside the guppy tank for a loong time without trouble. Since I'm re-doin my 5 gallon hex, I've decided to add some real plants to it and this is the only plant i can get my hands on at this time.

There are these brown strings coming out of it which are the roots.

Gee...if I didn't know any better, I'd say that's a pothos, which is a common houseplant in the US.

You are almost correct. I have both kinds: the household and i think, the aquatic. I checked the household one and it looks almost exactly like the one in the guppy tank except for the brown roots that extend from each stem.

Yay i found the answer:

Pothos and Philodendron - These are not aquatic plants, they are actually popular vine-like houseplants. However these plants do very well with their roots in just water (this is also how new cuttings of these plants are usually started) and are terrific at sucking out the ammonia and nitrates from the aquarium water. They also look nice draped all around the outside of your fish tank!
