Danio margaritatus
(Galaxy Rasbora / Celestial Pearl Danio)
Galaxy Rasboras (Celestial Pearl Danios) are a highly sought-after, elite nano fish prized for their striking combination of deep blue-purple body coloration and contrasting bright, iridescent pearly spots. This creates a bold, starry “galaxy” effect that delivers intense visual impact and a jewel-like presence in freshwater aquariums—especially in low-tech planted tanks, nano setups, dark-substrate aquascapes, or peaceful community aquariums.
Coloration & Appearance
Top-grade Galaxy Rasboras display a rich, saturated deep blue to blue-purple body covered in crisp, pearly white-to-gold spots that extend from the head through the flanks and tail—creating exceptional color depth, uniformity, and a sparkling, almost metallic sheen with virtually no dull or washed-out areas.
- Visual Impact: These premium specimens push the boundaries of nano fish aesthetics, featuring near-solid intense body tones with iconic “starry night” spotting that makes their pattern pop dramatically under aquarium lighting.
- Dynamic Hues: The coloration can subtly intensify or shift with mood, lighting, diet, and water quality, far surpassing average specimens in coverage, richness, and overall “wow” factor.
- Dimorphism: Males typically showcase the boldest, most vivid red-orange fins and sharper spotting, while females are slightly larger and rounder with more subdued tones, especially when carrying eggs.
Behavior & Lifespan
These lively, schooling fish attain an adult size of about 0.8–1 inch (2–2.5 cm), with a typical lifespan of 3–5 years in prime conditions.
- Active Schoolers: They are active midwater swimmers and excellent community nano fish, constantly exploring and interacting when kept in proper groups.
- Tank Presence: They add graceful movement and visual interest to your setup while remaining peaceful and non-aggressive toward compatible tank mates.
Care & Aquarium Setup
Galaxy Rasboras are beginner-to-intermediate keepers that prefer stable, slightly cooler freshwater parameters and do best when kept in groups.
- Ideal Parameters:
- Temperature: 70–76°F (21–24°C)
- pH: 6.5–7.5
- Hardness: Soft to moderate (roughly 5–15 dGH)
- Environment: They thrive in mature, well-cycled, densely planted tanks with gentle filtration, dark substrate, floating plants for cover, and open swimming space. Keep them in groups of at least 6–8 (ideally 10+) to reduce shyness and encourage natural schooling behavior.
- Breeding: They are egg-scatterers that will spawn readily in optimized planted environments when parameters remain consistent and the group is healthy and well-fed.
