I thought about that already and its what I wanted from the plant.
I want to create shade for my angels. Since this is a crypt tank, the area where I put the sword would shade green and brown wendtii, which don't need alot of light.
Also, I like the idea of adding some big plant to break line of sight as there is potential for some aggression with angels. Right now they all get along and are still sub adult stage. But anything to help divide some territory is not going to hurt any.
Here is a pic of the tank to give you can idea.
As for roots and getting to big, it shouldn't be a huge problem as I can simply keep cutting back leaves. I don't do any trimming in this tank because of my plant choices. Only time I break out my scissors is to trim really old leaves if they start to look bad. Maybe bi monthly.
If I ever wanted it gone I would just leave the roots in, cut all leaves and slowly kill it. I think that would work
