hi,
A few weeks ago i bought this plant as "water mat" but could not find any info on it and believe that is not even a plant's name. If anyone has any thoughts or knows what kind it is that would be greatly appreciated.
Thanks!

Naja Grass better known as Guppy Grass, when it's grouped together it can resemble moss but when it's separated or not grouped together it looks totally different...

Thanks, I think that is it and will try separating it, to see if it looks like that.
