Water Quality and Temperature

• Temperature: The Gold Zebra Danio Longfin thrives in a temperature range of 65°F to 75°F (18°C to 24°C).
• pH Level: The ideal pH level is between 6.5 and 7.5, making it adaptable to slightly acidic to neutral water conditions.
• Hardness: They prefer soft to moderately hard water with a range of 5-15 dGH.
• Filtration: A gentle filtration system is sufficient, as they are not particularly demanding when it comes to water movement.
• Water Changes: Regular water changes of about 20-30% weekly will help maintain optimal water quality and keep the fish healthy.

Feeding

• Diet Type: Omnivorous
• Staple Foods: Offer high-quality flake or pellet food designed for small tropical fish.
• Live and Frozen Foods: Supplement with live or frozen foods such as brine shrimp, daphnia, or bloodworms to provide variety and extra nutrition.
• Vegetable Matter: Occasionally, blanched spinach, zucchini, or algae-based foods can be added to their diet for additional fiber.
• Feeding Frequency: Feed small amounts 2-3 times a day to ensure they consume the food within a few minutes, avoiding any leftover food that could pollute the water.

Tank Mates

• Compatible Tank Mates: The Gold Zebra Danio Longfin is a peaceful fish and does well in community tanks with other small, non-aggressive species like tetras, rasboras, corydoras, and other livebearers.
• Avoid: Avoid keeping them with aggressive or large predatory fish, as they may be intimidated or preyed upon.
• Schooling Behavior: Danios are social creatures and thrive in groups. Keeping at least 5-6 individuals together ensures they feel secure and exhibits natural schooling behavior.

Substrates and Tank Decorations

• Substrate: Fine gravel or smooth sand is ideal for Gold Zebra Danio Longfins. It allows them to swim freely and comfortably.
• Tank Design: They appreciate a well-planted tank with a variety of hiding spots, but they also need plenty of open swimming space to accommodate their active swimming style.
• Plants: Live plants like Java Fern (Microsorum pteropus), Anubias (Anubias spp.), and Vallisneria (Vallisneria spp.) can add structure and visual interest to the tank. Floating plants are also beneficial for providing some shade and cover.
• Lighting: Moderate lighting is suitable, as these fish do well in a well-lit environment but can also appreciate some shaded areas within the tank.

Suitable Plants

• Floating Plants: Water Lettuce (Pistia stratiotes), Water Sprite (Ceratopteris thalictroides)
• Background Plants: Anubias (Anubias spp.), Java Fern (Microsorum pteropus)
• Midground Plants: Cryptocoryne (Cryptocoryne spp.), Amazon Sword (Echinodorus spp.)

Sexing

• Males vs. Females: In general, males are more colorful with a brighter gold hue and slightly smaller in size than females. Females tend to be rounder, especially when carrying eggs. Males also tend to have more elongated fins.

Breeding

• Breeding Behavior: Zebra Danios are egg layers and are relatively easy to breed in captivity. They are scatterers, meaning the female will release eggs that the male fertilizes after they are laid.
• Spawning Conditions: For successful breeding, place the breeding pair in a separate breeding tank with soft, slightly acidic water. Provide plenty of plants or a spawning mop for the eggs to adhere to.
• Fry Care: The eggs hatch in 2-3 days, and the fry are free-swimming shortly afterward. Feed the fry infusoria or freshly hatched brine shrimp.
• Parental Care: The adults will not care for the eggs or fry, so it’s best to remove them after spawning to prevent them from eating the eggs or fry.

Maximum Size and Longevity

• Size: Gold Zebra Danio Longfins generally reach about 1.5 to 2 inches (4-5 cm) in length.
• Lifespan: With proper care, they can live for 2 to 3 years, although they are often seen living even longer under ideal conditions.

A Fun Fact

Gold Zebra Danios are one of the first fish species to be genetically modified for scientific research, leading to the creation of fluorescent varieties. However, the natural gold variant remains a popular and beautiful fish in aquariums worldwide.
