Hey all, I just received my order from Black Jungle, and the cork bark I ordered came with dry lichens and "moss" on it. This cork bark is going to be half submerged in a paludarium. My question is this; Will this be harmful to the water/animals/fish? I wouldn't think so because it's natural, but will it get all moldy and gross, or will it re-generate and grow? Basically, is it ok to leave this stuff on it?? Thanks, pictures coming soon!!
