It's a fungus, quite common on new wood. It's quite harmless, if you don't like how it looks take it out & run boiling water over it & rub it off, it may come back for a while after though
I've no idea why it happens, just that it does & eventually it just goes away.
Yea some areas are completely cover in it.
Very common. Some fish may even pick at it. Just a harmless fungus that will go away on its own once the bacteria catch up.
Other than being somewhat unsightly looking. No harm to livestock.
Ok, it's weird I never had fungus grown on my other pieces I had in my old 55 gallon. I might be getting more pieces of driftwood will it grown on those too? What the fungus feeding on.Sorry. Yes the beneficial bacteria. It will go away on its own.
I personally freaked slightly when I added pre soaked mopanI in my main and a few days later had this goo all over the mopani. But everyone here is right. It will go away on it's own.
So fungus grows for what? To help the bb?Strange why but whenever you introduce anything new to an aquarium you need to give it time for BB to catch up ( why you don't add all your fish at once ).
It's a natural process.
