Can a Goldfish change it's color?

Recommended Posts

Hi I have a gold pearlscale. Well at least it was yesterday...today I got whiplash when I did a double take at feeding time. Goldie has black markings and they were NOT there yesterday. There is now black in her dorsal fin, at the base of the dorsal fin and on both sides.

Now IIRC I thought I read that black is a fugitive color in goldfish and could disappear but I don't remember reading anything about new colors popping up. I've had Goldie now for about 3 months and she was about an inch and a half long when I got her. She has since almost doubled her size. Can anyone let me know if this has happened to them.

Thanks!

the blackening of fins can be natural colour but in most cases is bad quality of water. i will be moving this to Diagnosis and Discussion forum. please take some time to answer all the questions asked in the white box at the top of the page. it will be very helpful if you can also provide some pictures of the new black marks shown on your fish.
