My experience with Anubias nana is that it can grow floating about as well
as rooted. It has small roots that cling to stones like ivy rootlets and
the roots have very small air passages in them, so I would not expect them
to do well in anaerobic mud in contrast to most other aquatic plants which
have much larger air passages in their roots. I grow Anubias in gravel
with only a small amount of mud, less than 1/4 inch, at the bottom.
Anubias appears to extract iron very will from the water. For me, it is
like a plastic plant that slowly grows. It seems almost indestructible.
It grows even slower than crypts, but it does very much benefit from CO2
additions and good light, although it will tolerate dim light. I have
never seen any snail damage to anubias with ramshorns and pond snails. I
can't imagine what is making the holes in your plant.
