I know its normal for it to happen and that I just need to wipe it off and eventually it stops growing fungus on it, just wondering as my fish seem to be eating it, is it going to harm them?

Ohhhh I have a BN in another tank, might fish him out and see how he goes with it![]()

Its there because its new wood and in a new tank. I knew it would get it, just didnt think the fish would eat it, the rainbows keep having a nibble. Yeah its just a fine white fungus, nothing sinister.
Was soaked for a few days and scrubbed well before adding it to the tank.
