You will really need to give us a lot more info. There is a disease questionnaire that needs to be filled out so you can get some help.
Just because you did a 75% change the night before doesn't mean all is fine and dandy. If those fish were swimming in old polluted water until that point then they have already been subject to and fighting off whatever is in there...
You really need to start with some big daily water changes and get us more info...
Do your other fish look as bad as this guy?
