I agree with vespers it would also be good to have water circulation.
You should look at some of those really cool Cryptocoryne habitat pictures from Borneo and other places in SE Asia. It would be awesome to recreate something like that. There were a couple of people (can't remember who??) who posted lots of pictures of those places on aquaticplantcentral.com.
