Java moss not doing well emersed? Psssh, as long as you can keep somewhat high humidity you will be A-OK. The problem with some mosses that you can find in temperate climates is that some (such as non-tropical pillow moss) require a dormant period. If they are not given this, they will eventually die. Personally, I would buy a fat bunch of Java off the forums here and use that.
Riccia fluitans can also do great, but it requires even higher humidity, though running water is best. For instance, if you want a stream section place your riccia along the "stream" bank. If given enough light, it will eventually grow over the water/above the bank in one thick mass.
How big is your tank? I would shoot for 1.5-2watts per gallon for a 20gallon tank
