It's hard to tell just by looking at them Caleb, the one on my 30 is for planted tanks with more peaks in the red and green light spectrum, but it still looks like it has a blue cast to it. Honestly, the lights that come with aquariums aren't much good for anything but lighting the tank, if you want to keep plants in freshwater you'll definitely have to upgrade the lights. The fixture I have for my saltwater tank is a 6 bulb unit, 4' long. It goes for over $800 new! Luckily I found a good used one!
