If you keep a goldfish in a dark room, it will lose its color. If you keep your fish in the dark all the time, the chromatophores won't produce more pigment, so the fish's color will start to fade as the chromatophores that already have color naturally die, while the new cells aren't stimulated to produce pigment. @googlefactss #fish #nowyouknow
