Care Requirements

Tank Size and Setup

A well-established, densely planted aquarium with a capacity of at least 10 gallons is recommended for a small school of galaxy rasboras. The tank should provide ample hiding places, such as aquatic plants, driftwood, and rocks.

Water Parameters

• pH: 5.0-6.0 (slightly acidic)
• Temperature: 75-80°F (24-27°C)
• Hardness: Up to 10 dGH (soft to moderately hard)

Achieving and maintaining these water parameters is crucial for the well-being of galaxy rasboras. Regular water changes and the use of water conditioners may be necessary to keep the water chemistry within the optimal range.

Filtration and Lighting

A gentle filter that provides adequate water circulation without creating excessive currents is essential. Galaxy rasboras prefer dim lighting conditions, so subdued lighting is recommended.

Diet

Galaxy rasboras are omnivorous and accept a variety of foods, including:

• Live foods (brine shrimp, daphnia, fruit flies)
• Frozen foods (bloodworms, Mysis shrimp)
• Commercial flake food
• Veggie-based flakes or pellets

Breeding

Galaxy rasboras are relatively easy to breed in a home aquarium.

Breeding Setup

A separate breeding tank of at least 5 gallons is recommended. Condition the breeding pair by feeding them a nutrient-rich diet for a couple of weeks.

Spawning Process

• Introduction: Introduce the breeding pair to the breeding tank and allow them to familiarize themselves with the surroundings.
• Courtship: The male galaxy rasbora will engage in a courtship dance, flaring his fins and chasing the female.
• Spawning: The female will release her eggs, which the male fertilizes. The eggs are typically scattered among the plants or on the substrate.
• Incubation: The eggs hatch within 24-48 hours. The fry are extremely small and require infusoria or very finely powdered food as their first meal.

Tips and Tricks

• Maintain a stable environment: Galaxy rasboras are sensitive to water parameter fluctuations.
• Avoid overfeeding: Overfeeding can lead to health issues.
• Dither with less aggressive fish: Galaxy rasboras are peaceful fish and may be intimidated by more aggressive species.
