No. This fungus comes from the wood itself. When i had it, I saw something was wrong and removed the wood, gave it a very good scrubbing in boiling water, then placed it in a tank with no fish. For about 3 months it looked fine, so I decided to use it in my fish tank, a different tank it so happens. A few weeks later I saw fish were dying fairly rapidly, and spotted some fungus on the back side of the wood. Out it came and into the garden.
I took this issue to a friend who is a microbiologist, and she said not to risk the fish, as there is no way of removing this unless one knows exactly what species, and even then, it may not be treatable.
I consider the $35 I spent on the wood as the price to learn a lesson.
