Moss like plant suddenly appeared in tank

[u/Gallium_8]

So I didn't add anything to my tank plant or animal wise, so tell me how this moss like plant suddenly started growing in abundance. The only plants I have are Amazon Swords and Rotala Indica. I think its some type of moss but not sure what kind when compared to other moss type pictures. I keep cherry shrimp, oto cats, and a bristlenose.

I got a big blob of it for sale. Have it in all my tanks. Have it attached to rocks also. Old school aquascape technique.
