I had considered the dwarf hair grass some. I know I've seen it at the petsmart near home, but I'm getting mixed answers as to whether or not they're "easy" plants.
This is coming from someone who somehow managed to kill anacharis >.<
(I think it might've been my LED lighting that's set up for the 2.5g, it was the only thing I could find for a tank that small)
Right now I have a 10w florescent bulb on the 5g, and I'm hoping that it's enough for the plants I have in there now, but would that be enough for the dwarf hair grass? I heard they prefer medium to high lighting.
