Love the Hydropiper! I am currently trying to plant my foreground with it, however be happy you have not added fish, they continuously pull it out on me! I can tell it begins growing, but then it stops once they yank it out. What jerks! Anyway the tank looks great, good luck with it! Buces would look great attached to those rocks! I have a handfull of stems of Pogostemon stellatus "Narrow Leaf" I could send you. PM me if interested!
