I finally got mine in and it looks great. I am just wondering if there is anyway to help it grow better or faster ?

I have it on driftwood mostly and one chunk on a rock on the floor ... not really planted just on the rock so that it can grow out.
I will be getting some Leaf Zone fert soon. I think I heard something about trimming it or trimming roots would help it grow but I'm not sure... may have been another plant.
Temp is staying at 78-79f and I know that they prefer 77 or lower but I'm afraid to drop it since my fish tend to get sick when I drop temps.
