What the heck is this stuff? I have algae of some sort in my newest tank that I assumed was hair algae, cuz it looked like a bunch of blond hair growing off my duckweed. Pulled all that out and am ordering shrimp. Didnt take a picture. Now I just noticed this green stuff growing in a different tank. It's totally different though. A branching clump, not long single strands. It's way finer than the java moss. I've got a couple pics of the remnants of hairy stuff from the other tank but it's hard to see.
