Hi everyone! I know sometimes bettas can have a gene that lets them change colors as they age. Not sure what that would look like, but my fish has started getting spots of new color and I am worried she might be sick... could someone please take a look at these photos and let me know if I should be concerned or if maybe she just has the color changing gene? Really hope it's the latter! She used to just be very dark blue and black...attaching a before image so you can see the changes.
