I belive thats the stuff ive been growing saintly, it not its a very similar species.
Id give it a try..... ive been trying to grow several types or liverworts, mosses and plagomnium in a spare tank on a windowsill, and all but 1 of the species ive tried have either grown or stayed alive for at least a month.
I do have to admit, the plagomnium ive tried has started to grow rather un-atractively.... as in from looking like a magnified moss to string with bubbles on it
None that have grown have harmed my fish or shrimps either

If that moss is the one i think it is it will reming you of pine trees when it grows

I was just thinking it would look stunning on and around some mini landscape rock
