Red Eye Tetra

The Red Eye Tetra (Moenkhausia sanctaefilomenae) is a small, vibrant freshwater fish native to the rivers and streams of South America, particularly the Amazon Basin. This species is easily recognizable by its shiny silver body adorned with distinctive red eyes and a subtle hint of iridescence. Adult Red Eye Tetras typically reach a size of about 5 cm, making them ideal for community tanks where their shimmering presence adds a splash of color.

In terms of behavior, Red Eye Tetras are known for their schooling nature. They thrive in groups of six or more, which helps to reduce stress and enhance their natural behaviors. These fish are generally peaceful and can coexist with various other species, making them an excellent addition to community aquariums. They exhibit active swimming patterns and display a curious demeanor, often exploring their surroundings in search of food.

Red Eye Tetras prefer well-planted tanks with ample swimming space and subdued lighting, mimicking their natural habitat. They are often found in slow-moving waters filled with vegetation, which provides both shelter and foraging opportunities. Maintaining a slightly acidic environment with soft water enhances their well-being and promotes natural behaviors, making them a joy to observe in a home aquarium.

This species is also known for its resilience to varying water conditions, though maintaining stable parameters is always beneficial for their health. With proper care, Red Eye Tetras can live up to five years in captivity, providing long-term enjoyment for aquarists.

For optimal care of Red Eye Tetras, maintain water parameters with a temperature range of 22-28°C, pH between 6.0 and 7.5, and soft to moderately hard water. Regular water changes and good filtration are essential to keep the environment clean and healthy. In terms of diet, these fish are omnivores and thrive on a varied diet that includes high-quality flake foods, micro-pellets, and occasional live or frozen foods such as daphnia and brine shrimp.

Compatibility is one of the key advantages of Red Eye Tetras; they generally get along well with other small, peaceful fish. However, avoid housing them with aggressive or larger species that might see them as prey. When introducing new fish, acclimation is crucial. Gradually adjust the new arrivals to the tank's water conditions over several hours to minimize stress.

Quarantine new arrivals for at least two weeks before adding them to the main tank. This practice helps prevent the introduction of diseases and parasites. By providing a stable environment and the right companions, Red Eye Tetras can thrive and exhibit their lively and colorful nature for years.

Red Eye Tetras are suitable for shipping, provided they are packed carefully to minimize stress. Use breathable bags with adequate oxygen and ensure a packing density that allows them space to swim without overcrowding. Maintain shipping temperatures between 22-28°C to prevent temperature shock during transit. These fish are not listed under CITES, which simplifies export regulations.
