Galaxy Koi Betta Breeding

Breeding these exquisite Galaxy Koi Bettas requires careful attention to conditions and stages. Let’s dive into the process step by step on how to breed galaxy koi betta successfully.

  • Setting Up the Breeding Tank: Prepare a 1-gallon breeding tank with a pH of 7 and maintain a temperature of 27°C or above. These conditions provide the ideal environment for successful spawning.
  • Selecting the Right Breeders: Opt for bettas under 1 year of age for optimal fertility. Ensure they are in prime health by pre-conditioning them with high-quality food and maintaining clean water conditions.

Typically, the female releases the eggs, which the male then fertilizes. Following this, the male collects and places the eggs into the nest. It’s crucial to move the female to a different tank afterward because the male tends to become more aggressive while guarding the eggs. Once the eggs hatch, it’s advisable to relocate the male to prevent him from preying on the fry.
