    This "mysterious" black stuff growing on your plants is a beloved
thing called algae.
     That is not what you should be worrying about though.  What the
real concern is, is why do you have a DIVER in your tank!!!  We notice
that you didn't mention that you had any "black stuff" on the little
treasure chest that opens and closes with air bubbles! (Few! thats
good!)
     
     It may not be algae though. Studies by the Dept. of Underwater
Management and Maintenance In Emergency Situation (DUMMIES)  have
shown that submersible toys , especially those embodying human
figures, can cause extreme trauma to those fish commonly found in
hobbyists aquariums.  This trauma causes the fish to excrete a
blackish substance coating the source of the stress, in hopes of
relieving the anxiety.
