Does it feel slimy? Like snot? If it does it is most likely a harmless fungus. I've only had it on new tank wood; not on plants. Does the tank have plenty of agitation/current? Or is it still-water?
Others might have differing ideas when it comes to plants.
If your dog thinks you are the greatest do not seek a second opinion
