I'm dry starting the tank right now. I feel like I ought to plant some stems to add some height, but I don't know what to plant.
I'll be getting some Downoi to tuck into the corners by the lantern and the driftwood, and I'm going to carpet the very front up to the glass with Fissidens fontanus. Plastic mesh is going to be a weeping moss wall.
Crepidomanes auriculatum, I got it from a fish store that orders it from Aqua Forest. It supposed to be "true aquatic", and from what I've read from other users is that it grows really slowly under water, but it does pretty well, and even better with CO2.
The other fern that looks like java fern I think is Bolbitis heteroclita, I got that from Petsmart. I'm just going to try it aquatic, and if it doesn't work out, will grow it emersed in my riparium.
