Hi, I have a fish in quarantine for the last 10 days (3 small size goldfish goldfish in a 50 gallons tank). Havent seen any signs of ich. However today I saw 2 small white dots in the fin. However it is already dark and even with the lights on I'm not completly sure if is ich, probably I'm going to wait until tomorrow to take some photos. But do you guys think it could be ich? In my experience when a fish has ich, it only take 3 or 4 days to show symptomps of ich, also I only saw one goldfish with the the white dots, the other 2 goldfish are looking fine.
