I have banana plants in my tank and shortly after I got them they had sent a few of their leaves to the surface. It is so neat to watch the leaves slowly move up to the surface every time I looked at them. They also send roots in the gravel around them so you might not want to have them floating about. The other thing I noticed is that the leaves seem to decompose after a short time of about three or four days after being fully spread out. I hope that any of this info has been helpful to you.
