Why is my goldfish turning white?
(First pic March 2026 vs second pic yesterday)
This is Kimchi! Not sure if they’re male or female. I got them as well at two others Nori and Miso back in March of this year. They’re currently in a 40 gallon breeder but now that they’re getting bigger I plan to upgrade them! The thing is Kimchi has been solid orange for months and seemingly over night they’ve started to turn white. Every day more white appears. Kimchi is acting normal and still eats like crazy. Water parameters are all where they should be. The tank does have some algae but that’s my bad for leaving the lights on a little too long. I know that goldfish can change color over time. But I thought it was more so black turning to the typical orange. Never heard of an orange goldfish turning white. My other goldfish Miso, for example had a black mustache that ended up turning orange. I just want to know if this is normal or if there is something to be concerned about? Thank you!
