Hey OP, if you go with fake plants make sure they are silk or some other non-rigid material. I have a densely planted low light tank. If you have java fern your light(s) might actually be scorching the leaves. Even low, direct light tends to burn some of my lace Java fern.
Some good plants are Hydrocotyle leucocephala (Brazilian Pennywort, prolific grower), Egeria densa (Ancharis/Elodea, fast growing and flowering), any Anubias barteri variety, or any Microsorum pteropus variety (Java fern, var. Windeløv is very pretty). These plants all tend to do well without CO2 injection and my infrequent adding of nutrients to the tank!
