Tank Lighting
Hello liljosh...
You have a couple of plants that require moderate light and you have a low light tank. The Java fern is a slow grower and can do well in low light. I have a number of them in my 55 Gs with less than a watt per gallon and they do very well.
This Egeria variety you have needs moderate light and CO2 to do well. Not a good choice for low light. I'm not a real plant expert, but I believe 80 degrees is at the high end for this plant.
Best to up the wattage on the lights and lower the temp a little more to the mid 70s or look for some low light plants, like Anubias, varieties of Cryptocoryne and some of the mosses.
