Does anyone know what this is?

Do I need better pictures or is it just a weird one?

does this look like your plant?

That looks to be like 'Green Hedge'. It's usually sold as an aquarium plant but they actually are specifically for terrariums. They will rot sooner or later.

Hmm no that's not it. This one has a very rigid stem that is mostly red/redish. It seems to be melting is spots which is why I thought it might not be a true aquarium plant. The roots form where the leaves meet the stem with none forming below the substrate.
Apart from that, the only distinguishing feature is the small spiky balls that form in the V of the leaves/stem.

Ok, so popular consensus seems to be green hedge, although mine looks very different from the images i've seen of it, its behavior certainly seems non aquatic so i'll pull it when I get home from work. Didn't much like it anyway

And damn my LFS for catching me again, that's the third time now. I'm buying online from now on, least that way I can research better before I buy.

Looks like green hedge to me. I don't know why they keep selling that one as an aquatic.

I have been meaning to try that as a riparium plant.

You can have mine!
