Hi all! I've been looking at pictures of cellophane bettas, which I'm assuming Shadowfax is. I've noticed he's getting darker markings where it used to be more of a 'smudge' of grey when I first got him. Now it's darkening into a black (healthy looking of course!) He's also growing in some grey scales here and there.
Those of you that have experience with coloration changes, what do you think? I'm very curious. (Before finding this forum I haven't really had any bettas drastically change colors!)
