		I had a similar difficulty with new Anubias leaves in a
tank with Ancistrus, Syno. Eupterus, Kribensis, and Congo Tetras.
Everything was fine for two years, and then suddenly somebody started
chewing on my Anubias.  Through trial periods of isolation in a
quarantine tank, I discovered that the Ancistrus was the root of my
difficulties.  Apparently, he had done such a good job of algae
deterrent that he was starving.  As I still required his tank cleaning
services, I returned him to the tank and began to offer him a few slices
of waterlogged cucumber a week.  The problem disappeared entirely.  

	Offhand Note:  In the process I discovered that Syno. Eupterus,
and to a lesser extent Pelviachromis Pulcher (Kribensis) also have a
peculiar fondness for pre-soaked cucumber.  No other non-loricarids I
have ever owned have taken to it with such gusto.  I have to add five or
six slices at a time to ensure that enough remains for the Ancistrus.
