Why is my flowerhorn always stressed

How long have you had him? How big is the tank? Is he the only one in it? Does he swim out more when the lights are off?

Could be a number of things. Do you treat your tap water with declorinator? Is your heater shorting out? What is the PH range? What are you feeding it? It is possible it's going to fade. I have had many fish fade and when they start they will have stress bars until they turn almost all black then peel. Also for the background, use blue or bright colored background. Avoid clear, white, or black. Same for the gravel. No white, no black. Also how long have you had the fish? If it's still fairly new it could be from people walking by or the tv.
