I guess if you want more advice we need to back up a second and answer some questions:
How long have you had the con? How big is it? How is it acting? What size tank is it in? What are the tankmates? What do you feed it? And have you added anything new to the tank recently?
But normally without for sure knowing what is going on I wouldn't recommend any other treatment other than maybe cut down on the amount of time the lights are on in the tank. This helps cut down stress a little.
I wouldn't also recommend any other treatment at this time because normally with all minor issues (which are most health issues with healthy fish) you can cure them with the increased water temp, salt, and time. Good luck and let us know what is going on.
