Hemigrammus erythrozonus, known as the Red Line Tetra, is a colorful and peaceful fish, ideal for community tanks with its striking red line.
Overview
Hemigrammus erythrozonus, commonly known as the Red Line Tetra, is a vibrant freshwater fish native to the Amazon Basin in South America. This species is renowned for the striking red line that runs along its body, contrasting with its silver base color. Typically reaching 4-5 cm in length, the Red Line Tetra is a peaceful, schooling fish that thrives in community aquariums. With a lifespan of 5-7 years, it adds a splash of color and liveliness to any tank setup.
Tank Requirements
The Red Line Tetra requires a well-planted aquarium with ample swimming space. A minimum tank size of 60 liters is recommended, with water temperatures between 22-28°C, a pH range of 6.0-7.5, and general hardness (GH) of 4-15. They prefer subdued lighting and dark substrates to highlight their vibrant colors. A gentle water flow is ideal, and the tank should be decorated with plenty of plants and hiding spots to mimic their natural habitat.
Feeding and Diet
In their natural habitat, Hemigrammus erythrozonus feeds on small invertebrates and plant material. In captivity, they should be provided with a varied diet that includes high-quality flake food, micro-pellets, and occasional live or frozen foods such as brine shrimp, daphnia, and bloodworms. Feeding small amounts multiple times a day helps to maintain their health and coloration. A balanced diet is essential for their overall well-being and longevity.
Care and Maintenance
Hemigrammus erythrozonus is relatively easy to care for, making it a suitable choice for beginners. Regular water changes of 20-25% weekly are important to maintain water quality. Since these fish are sensitive to poor water conditions, it’s crucial to monitor temperature, pH, and hardness regularly. Keeping the tank clean and ensuring proper filtration will help prevent common diseases. Regular health checks and maintaining stable conditions will contribute to their long-term health.
Compatibility
The Red Line Tetra is a peaceful species that fits well into community tanks. They should be kept in schools of at least six individuals to feel secure. Suitable tank mates include other small, non-aggressive fish such as rasboras, small tetras, Corydoras catfish, and dwarf gouramis. Avoid keeping them with larger or aggressive species that may see them as prey. Their peaceful nature and compatibility with various species make them an excellent choice for a harmonious aquarium.
Breeding
Breeding Hemigrammus erythrozonus in captivity requires some effort but is achievable with the right setup. A separate breeding tank with slightly acidic water (pH 6.0-6.5) and a temperature of 26-28°C is recommended. Provide a dimly lit environment with fine-leaved plants or a spawning mop for the female to scatter eggs. Conditioning the breeding pair with live foods will increase the chances of successful spawning. After spawning, remove the adults to prevent them from eating the eggs. The eggs typically hatch within 24-36 hours, and the fry can be fed infusoria or newly hatched brine shrimp until they grow large enough to accept larger foods.
