Brown apple snails eat the long variety of red algae.  I don't know whether 
that's beard or brush.  They don't appear to eat the short variety.  From what 
I've seen, the long variety grows in my tank under high light conditions when 
there isn't enough CO2 available.  It's about an inch long and grows in mats 
covering the leaves of my plants.  The color is a very dark reddish black.  The 
short variety grew in my tank when I wasn't using as much light.  It attached 
itself to fixtures and to the older leaves of my plants.  It was the same color,
 but had a velour texture.  This algae turned a very light green when I upped 
the lighting on the tank (my observation).  These may be two different growth 
patterns of the same algae.  I don't know, but the apple snails didn't seem to 
make as much of a dent in it.
