So, I want to get some vallisneria for my 50 gal tank. My intention is that they will grow tall enough to have the ends 'float' and provide a covered area in the tank. The tank is about 20" tall, and about 18" wide, so I would want something that will grow to between 30" and 40". Of course the upper end is ideal, if it gets too tall I can trim it; it needs to get to at least 30".
My question is: Which type of vals should I get?
