The Red empress shares king of the tank title with the yellow blaze.The t-reef has always been bullied by the empress.When he was in the 120 he was just beautiful.When I put the bass in the 120 he was moved with some other fish back to the 225 and he is slowly going back to the juvie look.
I had the same problem, you just are going to have to wait for like a year... It stinks but that was what happened with mine. (I also have another peacock that did the same and almost lost all color, he was wild caught to top it off..)
