Hello I am new to this website and I am relatively new to keeping fish. I've had a fancy goldfish for about 8 months and he is completely healthy and my aquarium water parameters are perfect. I didn't have any plans of adding a new fish to my tank but today I got a new fancy goldfish as a gift and didn't have a choice but to put him in my tank. I looked at him while he was in the bag and he looked healthy but after he was swimming in the tank I noticed he had a few white spots on his tail and on his front fins. I looked up ich and it doesn't really look like the pictures I saw. Anyway I was wondering what I should do if it is ich. I have a small aquarium that I can use as a quarantine tank but I don't know if I should stress him out further by putting him in another tank. Also will my other goldfish get ich even though the new fish has only been in the tank for a few hours? Sorry for my long question and thank you so much for your answer.
