Kauaidoug Posted May 3, 2021 Share Posted May 3, 2021 Hi, I have a 3 month old tank, no algae issues until I noticed this very close growing brown stuff on my mopani wood piece. There is a snail on the picture appears to be eating but my other cleanup crew avoid it, chinese algae eater and corys. Hopefully you can see it. I just noticed it and have no idea what this is. It is not really fuzzy. Should I clean this off. I haven't seen it anywhere else in tank. The first pic shows the darker brown in the middle of the lighter brown. I would say it is thicker than the lighter colored. The second pic is to show how close it is growing. Same brown spot as other image.
