clownfish wont eat/pits on head
I've had two clown fish for about 6 months. One tank raised one wild. The wild one won't close is mouth and stopped eatting for 3 day. He is find now but the tank raised clown did the same thing (open mouth, stopped eatting) but hasne't eaten in 5 days and has developed small pits on his head on his white strip. His mouth is now closed and is acting normal but still won't eat. The two fish I think are paired up and get along great and none of the other fish bother them or show and signs of illness.
I have no idea what is wrong or what to do
Water quality is perfect
