I have a VERY happy Anubias Nana that I bought a year and a half ago. It started small, but the happier it gets, the taller the leaves get, until now I have it growing out the top of my 15 gallon tank! I'm thrilled that it's doing so well, but any leaves that are no longer covered by water die very quickly. I'd prune off all the leaves that get too high, but it no longer sends up short stalks anymore, meaning I'd be essentially cutting everything off of my beautiful (if misguided ) plant. Does anyone have any suggestions?

Thanks!
