Hey people! Alright, after observing my betta, Ghost, I've noticed something different about him... At first he was absent of most color except for some black grizzle, so I figured he was a cellophane betta. I've only had him for two months and noticed significant changes.
The first photo is when I just got him.
The second is one month later- so you can see his body.
The third and fourth show how he is now. He is fairly dark.
I do understand the marble gene and how it works, but I'd like at least a second opinion. I've never had a marble. And I definitely didn't expect him to marble out because all the marble bettas I've heard of were colorful, not clear.
