I had a blue tang and a flame hawk on a 20G QT tank. Tang was hiding all the time so really didnt see him. But never so any signs of ich. Today it died 
.
On close exam it had a discolouration around the side fin of about 3/4 an inch diameter with here and there some bumps of same skin colour. Checked the water. Nh3 0 NO2 0.2 and NO3 1. Had done water changes last week.
Now on the hawk fish I see spots of pale areas all over its skin. He eats well and is active. Not even sure those spots are normal ?
Any suggestions ?
