Most of the time people assume the change of color in a Betta is negative, but in this case it's a marbling gene that causes the fish to change colors. November 8th when I purchased Isaiah, he was primarily white. I posted a photo of him back then showing at much.
Nov 8th
Here is Isaiah November 23rd with his changing genes. I think it's cool.
While a change in color of your Betta may be an indication of ill health, older age or water difficulties, sometimes it's simply genetics.
It's also noteworthy that when the fish is in the store it's a lot more stressed and not fed well and in a tiny bit of water. Once you bring home your Betta and give it proper care, the true colors will begin to shine.
