Hello guys have a bit of a problem I have a juv Emperor angel he is decent size think about to change. I had him for a year now in a 150g fish and coral tank big protein skimmer sump/fug whole nine yards everything been great all year he owns the tank and he knows it but the last week or 2 his colors have faded dramatically and his usually clear fins are looking a little raged and cloudy if that makes sense. I have also noticed little 1/2 circle indention on his face like someone took a bb and pushed it in his face 1/2 way then pulled it out. he is also a little twitchy and rubbing a little on rocks and is going to the cleaner shrimp a lot. sorry to be long winded just want to be thorough. plz help me I love this fish he is the prize of my tank
