Origin and Distribution

The Sunburst Orange Danio is a captive-bred color variant of the wild Zebra Danio. While the original species inhabits streams, rivers, and ponds in South Asia, this variant was developed through selective breeding to enhance its vibrant orange-gold coloration.

Colors and Markings

This fish is named for its sunburst-like golden-orange hue, often with faint horizontal stripes along its body. Some individuals may show a slight metallic sheen under bright lighting. Their streamlined body and forked tail make them agile swimmers.

Tankmates

Danios are peaceful and social, making them excellent for community tanks. Good tankmates include:

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

Avoid keeping them with slow-moving or long-finned fish like Betta fish, as Danios are known to be fin-nippers if kept in small groups.

Care Requirements

To maintain a healthy and active school of Danios:

• Use a minimum 20-gallon tank (long tanks preferred for swimming space).
• Keep them in groups of 6 or more to prevent stress and aggressive behavior.
• Provide moderate water flow to mimic their natural habitat.
• Include live plants (Hornwort, Java Fern, Anubias) and driftwood for shelter.
• Perform regular water changes (25-30% weekly) to keep water clean.
• Use a tight-fitting lid—Danios are known to be jumpers!

Diet and Feeding

Sunburst Orange Danios are omnivores, thriving on a varied diet. Ideal food options include:

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

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

Gender Differences

• Males: Slimmer with more intense coloration.
• Females: Rounder, especially when carrying eggs.

Breeding

Danios are egg scatterers, meaning they lay eggs in the substrate or among plants. To breed them successfully:

• Set up a separate breeding tank (10-15 gallons) with fine gravel or marbles to protect the eggs.
• Keep water at 24°C – 26°C (75°F – 79°F) and provide gentle filtration.
• Introduce a conditioned male and female and observe spawning activity.
• 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 crushed flakes.
