Mato Grosso Red Cherry Tetra

The Mato Grosso Red Cherry Tetra, scientifically referred to as Hyphessobrycon sp. “Muzel”, is a stunning and relatively rare freshwater fish native to the slow-moving, tannin-rich waters of the Mato Grosso region in Brazil. Known for its vibrant red coloration and peaceful schooling behavior, this species is highly sought after by aquarists looking for a unique centerpiece for their planted or blackwater aquariums. As it has not been formally described, it remains under its provisional designation.

Physically, the Mato Grosso Red Cherry Tetra features a vivid red body that glows under aquarium lighting, making it a standout in any setup. Its fins are typically translucent, with subtle highlights that enhance its overall appearance. Males often exhibit deeper red hues compared to females, especially during courtship. This tetra grows to about 1.5 to 2 inches (4 to 5 centimeters) in length, making it well-suited for medium-sized tanks or biotope aquariums.

In the aquarium, the Mato Grosso Red Cherry Tetra thrives in a natural, well-planted environment. A soft, sandy substrate combined with driftwood, leaf litter, and shaded areas created by floating plants provides the ideal conditions for these fish to display their best colors and behavior. As a schooling species, they should be kept in groups of six or more to reduce stress and encourage natural activity. A tank of at least 20 gallons is recommended for a group, with larger tanks allowing for more dynamic interactions.

Water parameters for the Mato Grosso Red Cherry Tetra should closely replicate its natural blackwater environment. They prefer soft, acidic water with a pH range of 5.5 to 7.0 and temperatures between 75 to 82°F (24 to 28°C). The presence of tannins, introduced through botanicals like Indian almond leaves or driftwood, can help create a more authentic habitat. Regular water changes and efficient filtration are essential to maintain water quality.

Feeding the Mato Grosso Red Cherry Tetra is easy, as they are omnivorous and readily accept a variety of foods. A diet consisting of high-quality flakes or micro-pellets supplemented with live or frozen foods like brine shrimp, daphnia, and bloodworms will keep them healthy and enhance their coloration. Providing a varied diet ensures optimal growth and vitality.

Breeding the Mato Grosso Red Cherry Tetra is possible but not commonly reported, as detailed breeding behaviors remain under-researched. Like other Hyphessobrycon species, they are egg scatterers and benefit from fine-leaved plants or spawning mops for egg deposition. After spawning, the adults should be removed to protect the eggs. The fry can be raised on infusoria or powdered fry food, transitioning to baby brine shrimp as they grow.

Overall, the Mato Grosso Red Cherry Tetra (Hyphessobrycon sp. “Muzel”) is a captivating and rare species that brings vibrant color and dynamic behavior to any freshwater aquarium. Its manageable size, peaceful nature, and adaptability make it an excellent choice for aquarists seeking a unique and eye-catching addition to their tank. With proper care, this tetra will thrive and become a striking highlight in any aquascape.
