Just an interesting observation I noticed this morning when I turned on the tank lights. The Neon Tetras were essentially colorless! I did not know that they lost their color at night. It takes less than a minute for them to all come out of hiding for the night and brighten up again. Even the "headlights" are off!!

Yup, fish use platelets to boost their colors, which require energy to function. As your fish "fall asleep", energy decreases & their colors fade. Fish do sleep :D
