I've got a 75 gallon tank and after adding CO2 (real CO2 not DIY) a few months ago my plants have really taken off. Now my problem is my Red Melon Sword is so big it is taking over a 1/3+ of the tank and the leaves are growing half way across the top. Is this plant just to big for a 75 gallon or is there some way of trimming it without hurting it.
