hi i have a 55 gallon tank with two floresent light bulbs side by side one is a power-glow and the other is some weird brand but would java fern or java moss grow in that. I dont want to get a new light set up or any of that stuff buy i would get new bulds (18in) or what kind of floresent bulbs would work? and if your going to tell me that i need a new hole set up dont bother!
