I was reading up on my Nymphaea lotus red, and remember something about how you can train the lilly to grow.

From APC's "Plant Finder"

N. lotus �Red� is a bulb plant which produces both submersed and floating leaves. Though the plant will grow under low light, higher light values should be favored by the aquarist if the formation of floating leaves is to be avoided. If these floating leaves do develop, however, it is often best to trim them before they get to the surface, since it will be difficult to discourage further foliage of this type once the plant knows where the surface is. Along these same lines, plants that already develop predominantly floating leaves can be trained to discontinue this growth habit if a vigilant trimming of developing floating leaves is practiced.

Hope that helps...
