A bred line with a yellow-to-orange gradient body — pale yellow head shading into orange toward the tail, like ripe marigold or pineapple.
Keeper tips for this variant
The yellow ground shows fin damage and disease (fungus, fin rot) readily, so it's a good early-warning fish — keep water pristine to preserve the clean gradient.
