Are you sure it is mopani? It sounds like fungus to me.
ah ok cheers polish ive done a bit of research and apparently it's harmless to fish and will eventualy just go. Also it is supposed to be common for pieces that have been soaked left to dry soaked and then put in an aqaurium.polish;2176148; said:I got that on 1/5 pieces I've bought, I just took it out and scrubbed it. It came back twice but after that never again. The fish didn't seem to care.
