Oh I can't take credit for the template! That's from the forum, when you go to the tropical emergencies section, the pinned thread is "start here with your emergency", the template is from there! Just copy/paste when someone missed it
OP, it looks like ich to me, the heat and salt methods are the best treatment.
not sure about the belly thing though, can you get a pic of the fish in the tank just normally, not being held?
Also yes,
@FishBearer9845 is right that the template gives us really useful info we need in order to be able to help. Since we can't see the tank and fish or run tests ourselves, the more info you can give us, the better! Just copy paste the template and fill in what you can
