These little guys are currently 1-2mm, scattered all over the walls of one of my tanks. They are clear, slimy, and gelatinous. They do not react when touched like Hydrozoa. I am sure they are not hydra(I have had hydra in tanks before). These little guys appear to be completely innocuous. Their branches have what look like leaves(moss like in appearance). I believe they are a type of algae but I have been unable to find any similar examples online. Any help in identifying these is greatly appreciated.
They are not hydra.
