Red Blue Colombian Tetra: A Vibrant and Hardy Aquarium Addition

Red Blue Colombian Tetra (Hyphessobrycon columbianus) is a stunning freshwater fish with shimmering blue bodies and bright red fins. These active swimmers bring energy and colour to aquariums, making them a favourite for aquarists. Their hardy nature ensures they thrive in various conditions, making them ideal for both beginners and seasoned fishkeepers looking for lively tank companions.

Size and Lifespan

Red Blue Colombian Tetras typically grow to 6–7 cm, making them a medium-sized species perfect for larger community tanks. With proper care, they can live for 3–5 years. To maximize their lifespan, ensure consistent water quality, regular feeding, and a stable environment. Their manageable size and longevity make them a rewarding addition to any setup.

Are Red Blue Colombian Tetras Aggressive?

These tetras are generally peaceful but can exhibit semi-aggressive behaviour, especially if kept in small groups. Fin-nipping may occur when they feel stressed or crowded. To minimize aggression, keep them in schools of at least six individuals. Additionally, providing a spacious tank with plenty of swimming areas and hiding spots helps reduce conflicts and promotes a harmonious environment.

Suitable Tank Mates

Red Blue Colombian Tetras are compatible with other active, robust species. Ideal tank mates include Danios, Barbs, and larger Tetras. However, avoid slow-moving or delicate fish like Angelfish or Bettas, as their fins may be nipped. A well-balanced tank with similarly active companions ensures a peaceful and lively aquarium.

Distinguishing Males and Females

Sexing Red Blue Colombian Tetras is relatively easy. Males are slimmer and display more vibrant red fins, particularly during breeding seasons. In contrast, females are rounder, especially when carrying eggs. Observing these traits becomes easier when they are in groups, where differences in body shape and colouration are more noticeable.

Breeding Red Blue Colombian Tetras

Breeding these tetras requires a separate tank with soft, slightly acidic water and temperatures between 24°C and 26°C. Include plants or spawning mops for egg-laying. Males will court females, who scatter eggs among the plants. After spawning, remove the adults to prevent them from eating the eggs. The eggs hatch in 24–36 hours, and fry should be fed infusoria or finely crushed fry food.

Caring for Red Blue Colombian Tetras

These tetras thrive in tanks with open swimming areas and plants for cover. They prefer water temperatures between 22°C and 28°C and a pH range of 6.5–7.5. Regular water changes and efficient filtration are crucial to maintaining water quality. Adding a dark substrate and subdued lighting enhances their colours and reduces stress, helping them stay active and healthy.

Feeding Red Blue Colombian Tetras

As omnivores, they require a varied diet to remain healthy and vibrant. High-quality flakes or pellets should be their main food source. Supplement with live or frozen options like brine shrimp, daphnia, and bloodworms for added nutrients. Occasionally offer blanched vegetables like zucchini or spinach to support digestion and boost overall health. A well-rounded diet ensures they maintain their striking colours.
