Denison barb top fins are changing color

[The_Desacrator]

So one of my denison barbs (had about about a month maybe) has had his top fin and part of body change color. Idk if he came that way and I didn't notice. Is anything wrong with him? Or is that natural? Everyone is eating and swimming fine no signs of any problems

Pics in next post.

Water parameters? Ammonia /nitrite /Nitrate /

Any other fish picking on him?

Do you have lunar lights so you can sit back away from the tank and watch their behavior to make sure he isn't being bullied?

Looks like his color is becoming more normal

Color changes are in more than one place now.
