What makes a Galaxy Koi Betta different from a normal Koi Betta?

Galaxy Koi Bettas combine koi-style marbling with metallic galaxy speckles, giving a brighter, more iridescent appearance than standard koi bettas.

Do Galaxy Koi Bettas change colour over time?

Many Galaxy Koi Bettas continue to develop and intensify their colours as they mature, especially with stable warm water and good nutrition.

Do Galaxy Koi Bettas need a heater?

Yes, Galaxy Koi Bettas are tropical fish and require stable warm temperatures between 24–28 °C (75–82 °F).

Are Galaxy Koi Bettas suitable for beginners?

They are suitable for beginners who can maintain clean, warm water, gentle flow, and a safe, fin-friendly environment.

Can Galaxy Koi Bettas live with other fish?

Galaxy Koi Bettas can live with peaceful, non–fin-nipping tankmates, but males should never be housed with other male bettas.
