I'll check out the Pothos and see if I can find one I really like. They aren't a group I've looked into much so I'll have to do my research.
O and I realized that I haven't said anything about lighting. It'll either be a 15W 6700K bulb or 2 10W 5800K bulbs. Just depends on what hood I decide to use.

Checking out www.joshsfrogs.com I came across the Black Rabbit's Foot Fern, which I really like. May try that as the larger plant in the corner.

Anyone know how Creeping Jenny (Lysimachia nummularia) would do in a setup like this. Would like to have it growing out of the water over the moss.
