Java moss, java fern, Anubias nana and many Crptocorynes are recommended for low light situations. That does not mean that they need low light but just that they will survive and grow in low light. Java moss and java ferns have a home in many of my tanks. Some of the tanks are low tech, low light tanks. Others are medium light, pressurized CO2, artificial fertilizer tanks. The java ferns and java moss grow faster in higher light but do fine in the low light also, I would class them as versatile plants. They will grow for you whatever situation you have. I think you could actually grow java moss with just room lights. I have a few scraps that got into an unlighted tank along with decor that I was moving and it is alive after 2 months now. Since the tank has not been cycled yet, the lights are not even plugged in on that tank. Who needs the algae with no fish or plants?
