Fun Facts
- The “Galaxy” pattern comes from the marble gene, meaning their colors can change over time, sometimes dramatically
- The platinum metallic shine is caused by specialized reflective scales, giving a near “chrome” effect under lighting
- Halfmoon bettas are named because their tail forms a perfect semicircle (180°)—a highly prized trait in competitions
- Despite their aggressive reputation, bettas are actually intelligent and curious, often responding to movement outside the tank
- In Thailand, bettas were originally bred for fighting competitions, but today varieties like this are bred purely for beauty
