Origin and Distribution

The Galactic Purple Danio is a captive-bred color variant of the wild Zebra Danio (Danio rerio). The original species inhabits streams, rivers, and ponds in South Asia, while this particular variety was developed through selective breeding to enhance its deep purple and metallic blue coloration.

Colors and Markings

The Galactic Purple Danio is named for its shimmering purple and blue tones, resembling a galactic nebula. Some individuals may exhibit hints of silver or pink under certain lighting conditions. Their streamlined body and forked tail make them highly agile swimmers.

Tankmates

Danios are peaceful schooling fish, making them ideal for community tanks. They do well with:

• Other small schooling fish (Neon Tetras, Rummy Nose Tetras, Harlequin Rasboras)
• Livebearers (Guppies, Platies, Mollies)
• Corydoras Catfish
• Dwarf Gouramis
• Snails and Shrimp

Avoid housing them with slow-moving or long-finned fish like Bettas, as Danios can be fin-nippers if not kept in a proper group.

Care Requirements

To maintain a healthy and active school of Danios:

• Use a 20-gallon tank (minimum) for a small group, though a 30-gallon tank is better for larger schools.
• Keep them in groups of 6 or more to prevent stress and aggression.
• Ensure moderate water flow, mimicking their natural habitat.
• Provide live plants (Java Fern, Hornwort, Anubias) and driftwood for hiding spots.
• Perform regular water changes (25-30% per week) for optimal health.
• Use a secure lid, as Danios are known to be jumpers.

Diet and Feeding

Galactic Purple Danios are omnivores, requiring a balanced diet to maintain their vivid coloration. Ideal food options include:

• High-quality micro-pellets and flakes (preferably color-enhancing varieties)
• Live/frozen foods (brine shrimp, daphnia, mosquito larvae)
• Blanched vegetables (zucchini, spinach, cucumber)
• Freeze-dried bloodworms as an occasional treat

Feed them small portions 2-3 times a day, ensuring all food is consumed within a few minutes.

Gender Differences

• Males: Slimmer and more vividly colored.
• Females: Slightly rounder, especially when carrying eggs.

Breeding

Danios are egg scatterers, meaning they lay eggs in substrate or plants rather than caring for them. To breed successfully:

• Set up a separate breeding tank (10-15 gallons) with fine gravel or marbles to protect eggs from being eaten.
• Maintain a stable temperature of 24°C – 26°C (75°F – 79°F).
• Introduce a conditioned male and female and observe spawning behavior.
• After spawning, remove the parents to prevent them from eating the eggs.
• Eggs hatch in 2-3 days, and fry can be fed infusoria or finely crushed flakes.
