Right now my goldfish is turning white. She was all orange as a baby, and a few months ago she began to turn white. She stopped turning white after about a month, and became half white and half orange. But recently she has been turning all white. Her fins have remained almost all orange, and she is still orange around her mouth. She seems just as active as ever. I don't know what type of goldfish she is(by the way I'm not sure she's a she) I won her at a carnival but I've had her for over a year now. I would not be so worried if the change was gradual, but it is happening pretty quickly. Her fins are still in perfect form, and her scales seem normal. I don't think the white is fungus, her scales are actually white. She's about 3-4 inches long. Her tank is 2 or 3 gallons, and she is the only thing in it. She has lived in it all of her life. I have not changed the location of her tank, or any decorations in it. I cleaned it about a week ago, and I think I did it the same way as always. I changed her food 2 or 3 months ago, and am currently feeding her Tetrafin goldfish crisps. The room that her tank is in is lit most of the time just by sunlight, but the sun doesn't shine directly into her tank. I do not have a light for the tank. I only have an airstone in her tank, no filter. I was planning on buying her a 5 to 10 gallon tank with a filter soon. Would this help? I love my goldfish, and I don't want anything to happen to her. Should I get her checked out? What should I do? Please answer this if you are certified with fish, or if you work with fish. Also, has this happened to anyone elses goldfish? Please help me!
