For the best GloFish viewing experience, try using a blue wavelength light, like GloFish LED lighting, to give a uniquely fluorescent look, particularly in low or nighttime lighting. Traditional white aquarium lights (such as fluorescent or halogen lights) work well for daytime use. GloFish fluorescent fish absorb light and then re-emit it, so they will appear brighter and more vibrant as the amount of light is increased. GloFish fluorescent fish are born brilliant!
