Galaxy Rasbora Care Guide with Aquarium Size Requirement:

1. Species Overview:

• The Galaxy Rasbora (Celestichthys margaritatus) is a small and captivating freshwater fish known for its vibrant colors and distinct celestial patterns. Originating from Southeast Asia, it has gained popularity among aquarium enthusiasts.

2. Aquarium Size:

• Provide a tank with a minimum size of 10 gallons for a small group of Galaxy Rasboras. A larger tank, around 20 gallons or more, is recommended for a community setup with multiple fish species.

3. Water Parameters:

• Maintain a stable water temperature between 73°F to 81°F (23°C to 27°C).
• Aim for a slightly acidic to neutral pH level, ideally between 6.0 and 7.0.
• Keep the water hardness in the soft to moderate range, around 5 to 15 dGH.

4. Size of the Fish:

• Galaxy Rasboras are tiny, typically growing to a size of about 0.5 to 0.8 inches (1.3 to 2 centimeters).

5. Tank Decor:

• Create a well-planted aquarium with floating plants, providing shaded areas. Use dark substrate to enhance the colors of the Galaxy Rasboras.
• The addition of driftwood and small caves can create hiding spots and mimic their natural habitat.

6. Diet:

• Galaxy Rasboras are omnivores. Feed them high-quality micro pellets, flakes, and small live or frozen foods like daphnia, brine shrimp, or micro worms.
• Offer a varied diet to ensure proper nutrition and enhance their colors.

7. Behavior:

• Galaxy Rasboras are peaceful and thrive in schools. Keep them in groups of at least six individuals to reduce stress and encourage natural behavior.
• They are active swimmers and tend to stay in the mid to upper levels of the aquarium.

8. Tank Mates:

• Choose peaceful tank mates of similar size. Ideal companions include small tetras, dwarf shrimp, or other non-aggressive small fish.
• Avoid keeping them with larger or aggressive species that may intimidate or prey on them.

9. Tank Maintenance:

• Regular water changes of 20-30% every week are crucial to maintain water quality.
• Use a gentle filtration system suitable for a smaller tank.

10. Breeding:

• Galaxy Rasboras are egg scatterers. To encourage breeding, provide fine-leaved plants or spawning mops.
• Transfer the adults to a separate breeding tank to increase fry survival, as they may consume their own eggs.

By following these care guidelines and providing an appropriately sized and well-decorated aquarium, Galaxy Rasboras can flourish, showcasing their stunning colors and contributing to the beauty of a community tank.
