When you type you can put it in all one post btw.

Anyways your fish doesn't seem like a fader but what can cause it is stress, mating ritual, and water quality. From what I hear that food is actually bad for the fish it contains like 60% protein.

Turn off the lights add salt and don't feed in two days see if he gets better.
