My 10 Gallon currently has some of the plants I plan to use:
*Micro Sword Grass
*Baby Dwarf Tears (Possibly)
I had Riccia, all kinds of moss, and a bunch of beginner plants I got from my LFS. I chose to use only the Hairgrass and Micro Sword Grass because they remained very healthy and spread fairly quickly without CO2.
My good friend actually introduced me to Aquascaping about 4 months ago and I've been pretty consumed with the hobby. I'll post some pics of his before/after photos - they are pretty awesome!
