Pictures? Without positive identification can't really say.I have on a piece of my driftwood a white fungus looking substance is this dangerous for my fish?
If so what do I do?
Is it a fuzzy looking fluffy kind of thing?
I've had it on a few pieces of wood with no problems but i'm not sure if it's dangerous or not and i've just been lucky.
If you can't get a picture up, i'll try one of mine so you can compare.
