It's the same color of the algae on my mopani log :X

So I don't really want to move everyone just to find out it was poo or fur but the more I watched it the more I think it is poo. My fantail has been looking more and more like a girl lately so I also wonder if maybe it's reabsorbed eggs but that specific uh, piece was not over there until I scared my pleco to the right side of the tank.
I saw some stuff in my betta tank that was significantly smaller but he ate it right up so I'm not even going to worry about him :p
