Hi! I have a comet goldfish that is about the size of my pinkie finger. He's currently living in a 10 gallon tank with a filter (I'm planning on upgrading when he gets a bit larger) and I noticed that a few of his scales aren't shiny (approximately 4 or 5). They're not fuzzy, and I only notice them when the light shines on him. Behaviorally, he's very active and appears happy, and he shows no other symptoms than those discolored scales. I was wondering if these scales are a sign of some sort of bacterial infection? This may or may not impact his scales, but I've been treating him for ich for the past 4 days with half doses of medication, and the white spots are all gone (I'll still treat him for another week or so, just to make sure that it doesn't return).
