Hi, I found this several months ago and it barely grew ever since I noticed it. It holds quite strongly to the rock and hasn’t spread at all. The only thing that changed is the fuzz growing at the tip of the stick. I thought that hair algae was growing on it, so I cleaned it up and that’s when I noticed that it came from the stick. Yes, I called it the stick because it looks like one. Any idea of what this is? It’s still super tiny.
