Environment for Breeding: Breeding galaxy rasbora requires careful attention. To initiate the breeding process, we should provide near to the natural environment. The aquarium should have a plantation with gentle water flow. Moreover, water temperature should be ideally around 22 to 26°C. pH of Water is slightly acidic pH, around 6.0 to 7.0. We should provide an array of fine-leaved plants for females to deposit eggs.

Group Size for Breeding Galaxy Rasbora: A group of six fish with half males and half females is appropriate for breeding Galaxy Rasbora Fish. This encourages natural behavior and enhances the breeding Galaxy Rasbora.

Male and Female Difference: Males and females of the Galaxy Rasbora fish exhibit clear sexual dimorphism. Males display vibrant colors, pronounced fins, and distinct spots on their bodies. On the other hand, females have softer, more subdued color patterns.

Behavioral Changes: Female galaxy rasboras tend to become plumper when they are ready to spawn. It is helpful to observe their behavior closely, as they often engage in courtship activities before laying eggs. Spawning usually occurs in the early morning hours.

Process of Breeding Galaxy Rasbora: During each spawning period, a female produces approximately 30 eggs. These eggs are neither free-floating nor attached to surfaces but are carefully concealed within dense vegetation. Males often follow spawning pairs and attempt to fertilize the eggs.

Hatching: The larvae typically hatch within 3-4 days. After 8-10 weeks, they undergo metamorphosis and develop into fully-formed adults.

Careful attention to breeding galaxy rasbora will result in the successful hatching of eggs.

Parental Galaxy Rasbora Care

Micro Galaxy Rasbora, Galaxy Danios, or Celestial Pearl Danios shows limited parental care. Even adult fish can eat eggs. So after spawning adults should be separated from the eggs.
