I have a 120 gl tank i have 3wts per gl. But by the time it get to the bottom of the tank it is like 2 1/2 wts per gl our lower. Because the tank is 24{in} tall.So the ? is what is a good foreground plant?
I'd say HC is the best foreground plant out there... it looks great... you might be able to pull it off in your tank, but if you're worried about the light, dwarf sag ought to do well too.
