Majestic Angelfish Concern

My flagfin loved it, would eat my fingers if I dipped them into it...
Unfortunately mine died shortly after the symptoms you described. It was the most curious lovable fish till it hid for a couple days not eating. Died after a couple days. Not to be a downer, hope yours makes it.

 

Thanks but yes you just killed my mood. I am completely lost on his behavior. The undisputed king of my tank is in hiding and will not eat. He is alert....just not eating and hiding.
