So, i grown a liking to amazon swords, i dont have any, but i feel they will fit the empy spot in my tank perfectly, and my lfs has a few really nice ones for sale. But my problem is i have a low light tank. Currently i have the 29 gallon Marineland LED Starter tank lights, that has an LED light that produces a total of only 4.62 watts. I dont know the color spectrum. Im just wondering will swords survive in my tank. I might add one of the those surmergable lights that marineland offers to add some light.
