Well this isnt really something wrong with my betta as much as what is wrong with the tank. I dont really know where to make this thread, I will post it Plants too but Im not sure if it is a plant. It is a brown algae like substance that is forming on the decorations. It doestn appear furry or fuzzy more of just a dirt or goo. The pictures make it look like everything is covered in brown but really its just the two big "column" structures and the center divider, there is also a bit coming off the lip of the filter. The water looks fine, its not floating around in there or anything. I tried to scrape off a majority of it last time it appeared about 2 weeks ago, but it came back. I am keeping up on water changes and everything so I dont know what to do. Would any kind of snails help kill it.
