Color changes are perfectly normal for this breed, thanks to that marble gene. It’s like their colors have a little magic, changing with the fish’s mood, age, or environment. Don’t worry; it doesn’t mean your betta is sick. Instead, it adds to their charm and uniqueness!

Feeding your betta well is key to keeping those beautiful colors bright. High-quality betta pellets or flakes packed with protein are a great staple.

How Do Blue Marble Dot Bettas Interact with Other Fish?
