Buying Guide: Key Purchase Considerations
What size tank do you have? Koi galaxy bettas vary in presence; larger tanks better showcase color and give fish ample swimming room. For beginners, start with 5–10 gallons per betta and gradually increase with multiple fish only if the tank is properly filtered and heated.
What water conditions matter? Maintain stable temperatures between 76–82°F (24–28°C), with a pH around 6.5–7.5 and moderate water flow. Avoid drastic temperature swings to reduce stress and disease risk.
What about compatibility? Bettas can be territorial; plan tank mates carefully. Use secure lids and tall hides to minimize aggression and provide retreat spaces for all fish.
How important is feeding? Offer high-quality pellets or flakes and provide occasional live or frozen foods to support coloration and health. Avoid overfeeding to prevent waste buildup.
Decor and hiding spots: Provide plants, rocks, and decorative elements that offer cover. Bettas appreciate gentle currents and ambient lighting that enhances their color without causing stress.
