The Bloodfin Tetra, scientifically known as Aphyocharax anisitsi, is a small and captivating freshwater fish species that is prized for its striking appearance and peaceful demeanor. Originating from the clear, slow-moving waters of South America, particularly in the Paraguay and Paraná river basins, these tetras have become a popular choice among aquarists for their vibrant coloration and ease of care.
Appearance: Bloodfin Tetras are named for their distinctive blood-red fins, which set them apart from other tetra species. These fish have an elongated body that is primarily silvery or pale gold in color, providing an excellent backdrop to showcase their vibrant fins. The dorsal and anal fins of Bloodfin Tetras are adorned with a deep crimson coloration, creating a stunning visual contrast against their metallic bodies. Their eyes are large and shiny, and their scales are small and well-defined, contributing to their overall attractive appearance.
Behavior and Personality: Known for their peaceful nature, Bloodfin Tetras are excellent community fish that can thrive in a group of their own kind or alongside other non-aggressive species. They are active swimmers, often darting and schooling together, which can create a visually pleasing display in the aquarium. These tetras are known for their gentle disposition and make a wonderful addition to community tanks.
Habitat and Care: Bloodfin Tetras are relatively hardy and easy to care for, making them suitable for aquarists of all experience levels. To provide them with an optimal environment, maintain an aquarium with a capacity of at least 20 gallons. Ensure that the tank is well-planted with areas for hiding and swimming. Maintain stable water parameters, including a temperature range of 72°F to 78°F (22°C to 26°C) and a slightly acidic to neutral pH level (around 6.5 to 7.5).
Diet: These tetras are omnivorous and have a varied diet. They readily accept high-quality flake foods, pellets, and freeze-dried or live foods such as brine shrimp, daphnia, and bloodworms. Providing a diverse diet will help keep them healthy and vibrant.
Compatibility: Bloodfin Tetras are excellent community fish and can be housed with other peaceful species that share similar water parameter requirements. Avoid keeping them with aggressive or fin-nipping fish, as their long fins can make them vulnerable to harassment. It's best to keep them in groups of five or more to help reduce stress and encourage their natural schooling behavior.
