Tetra Sunburst Orange: A Vibrant Addition to Your Aquarium

Characteristics

The Tetra Sunburst Orange is a stunning freshwater fish belonging to the Characidae family, well-known for its small size, peaceful temperament, and striking orange hue. It thrives in planted community tanks and is an excellent choice for both beginner and experienced aquarists. This species prefers:

• Water Temperature: 22–28°C (72–82°F)
• pH Level: 6.0–7.5
• Water Hardness: Soft to moderately hard (3–12 dGH)
• Tank Size: Minimum 10 gallons
• Behavior: Peaceful, schooling fish
• Care Level: Easy

Origin and Distribution

The Sunburst Orange Tetra originates from South America, primarily found in the Amazon River Basin, where it inhabits slow-moving streams and tributaries. These waters are typically rich in vegetation, providing them with ample hiding spots and a natural diet of small invertebrates and plant matter.

Colors and Markings

The Sunburst Orange Tetra is renowned for its brilliant orange coloration, which intensifies under proper lighting and optimal water conditions. It has a torpedo-shaped body, translucent fins, and a shimmering golden undertone that enhances its fiery appearance.

Tankmates

This species is a peaceful schooling fish, best kept in groups of at least six to encourage natural behaviors. Compatible tankmates include:

✅ Other small Tetras (Neon, Ember, Rummy Nose)
✅ Rasboras
✅ Corydoras Catfish
✅ Gouramis (small species like Honey Gourami)
✅ Dwarf Shrimp (if not too small)

🚫 Avoid aggressive fish like Cichlids or fin-nipping species such as Tiger Barbs.

Care Requirements

Maintaining a healthy environment is crucial for the longevity of Sunburst Orange Tetras. Ensure the tank has:

• Stable water parameters with frequent water changes (20% weekly).
• Live plants (Java Fern, Anubias, Amazon Sword) for hiding spots.
• Moderate lighting, as overly bright conditions may cause stress.
• A gentle filtration system, replicating their natural slow-moving waters.

Diet and Feeding

Sunburst Orange Tetras are omnivorous, requiring a balanced diet of:

• High-quality flake or micro-pellet food
• Frozen or live foods (daphnia, brine shrimp, bloodworms)
• Vegetable-based foods (spirulina flakes, blanched spinach)

Feeding small portions twice daily will keep them healthy and vibrant.

Gender Differences

Males tend to be slimmer with more intense coloration, whereas females appear rounder, especially when carrying eggs. During breeding season, males often display brighter hues to attract mates.

Breeding

Breeding Sunburst Orange Tetras in captivity requires:

• A separate breeding tank with soft, slightly acidic water (pH 6.0–6.5).
• Fine-leaved plants or a spawning mop to protect eggs from predation.
• Dim lighting, as bright lights can deter spawning.

Females scatter adhesive eggs among plants, which hatch in 24–36 hours. The fry should be fed infusoria or finely crushed flakes until they grow large enough for regular food.
