I put a piece of bogwood in my tank a few weeks back. I washed it and soaked it before putting it in my tank. Since being in my tank with my catfish and 2 danios, it seems to be growing a fungus type thing on it. Its slimy and white and kinda fluffy looking. I have washed it off but it seems to be growing back again. My water is fine (Have done tests) so Im wondering what it actually is called and is it good or bad?
