Hello...  Could someone give some advice on how to get my LILLAEOPSIS 
to grow.  I have a 55 gal tank DIY CO2, 160 watts of flourescent 
lights.  PH 6.5 TO 6.8 MEDIUM HARD WATER.  All my other assorted     
plant are growing thickly but my LILLAEOPSIS hasn't done any thing 
but sit there the last 5-months that I've had them.  Any help will be 
appreciated.  Thank you  Mike Bernardoni   mikeb at pso_siu.edu
