hi and help

Hi, I am not a newbie to keeping fish but am a newbie to the forum so first things first - hello to everyone. Now down to business - I have a common goldfish who seems to be losing weight and just recently I have noticed reddening around its right gill and right fin. He often seems lethargic but brightens up when fed. All other fish in the tank are fine. Any ideas?
