Sky Blue Tetra

The Sky Blue Tetra (Boehlkea fredcochui) is a captivating freshwater fish native to the rivers and streams of South America, particularly in the regions of Brazil and Paraguay. This species is known for its striking iridescent blue hue, which can create a mesmerizing display in any aquarium. Adult Sky Blue Tetras typically grow to a maximum size of around 5 cm, making them a suitable choice for smaller community tanks as well as larger setups.

Their body is slender and elongated, featuring a distinctive lateral line that runs along its side. The vibrant coloration of the Sky Blue Tetra is accentuated by its transparent fins, which often reflect light beautifully. In terms of behavior, these fish are known for their schooling nature; they thrive in groups and display more vibrant colors when kept in small schools of six or more. Their peaceful disposition makes them compatible with a variety of other community fish, enhancing the overall tranquility of the aquarium environment.

In their natural habitat, Sky Blue Tetras inhabit slow-moving waters, often among dense vegetation and submerged structures. They prefer areas with plenty of cover, which provides safety from predators. This species is typically found in slightly acidic to neutral waters, where they can exhibit their natural behaviors. Mimicking these conditions in captivity is essential for their well-being and longevity.

Overall, Sky Blue Tetras are not only visually appealing but also contribute to a balanced aquarium ecosystem. Their active swimming patterns and social interactions make them a favorite among aquarists, providing an engaging display for those who appreciate the beauty of freshwater fish.

To maintain healthy Sky Blue Tetras, aquarium importers and retailers should ensure specific water parameters are met. The ideal temperature range for these fish is between 22°C and 28°C, with a pH level of 6.5 to 7.5. It is crucial to provide a well-filtered tank that mimics their natural habitat, including plants and hiding spots to create a comfortable environment. A minimum tank size of 80 liters is recommended to accommodate a school of these active fish.

Feeding Sky Blue Tetras is straightforward, as they are omnivorous. A varied diet consisting of high-quality flake food, frozen or live brine shrimp, and daphnia will help maintain their health and vibrant coloration. It's important to feed them small portions multiple times a day rather than one large meal to prevent overfeeding.

When introducing Sky Blue Tetras to a new aquarium, acclimation is key. Gradually adjust them to the new water parameters over a period of a few hours before adding them to the tank. Quarantine new arrivals for at least two weeks to monitor for any signs of disease or stress. Their peaceful nature allows them to coexist with other community fish, but caution should be exercised when housing them with more aggressive species.

Sky Blue Tetras are relatively hardy and can be shipped successfully with proper care. The ideal packing density is around 1 liter per fish, ensuring enough space and water quality during transit. They are sensitive to extreme temperature changes, so maintaining a stable temperature range between 22°C and 28°C during shipping is essential. As a non-CITES species, they do not have special export restrictions, making them easier to trade internationally.
