General Description
The Bloodfin Tetra (Aphyocharax Anisitsi) is a hardy species belonging to the Characidae family, commonly found in the Paraná River drainage in Brazil, Paraguay, and Argentina. It can reach a maximum size of 5.5cm and is known for its longevity, with captive specimens living over ten years. This species is well-suited for beginners due to its adaptability to various tank conditions, even thriving in unheated tanks though coloration may be affected.
Aquarium Setup
For optimal care, the Bloodfin Tetra thrives best in a minimum tank size of 60 liters with a planted environment containing dense vegetation and open swimming spaces. Decorate the tank with twisted roots, bogwood, and floating plants as they enjoy swimming in the upper levels. A tightly-fitting cover is essential to prevent the fish from jumping. (See table for specific water condition requirements.)
Behaviour
This tetra is generally peaceful but may nip at long-finned or slow-moving tank mates. To mitigate this, it's recommended to keep them in a mixed shoal with other characids, Corydoras catfish, and small Loricariids. They are shoaling fish that thrive best in groups of at least six, showcasing their natural behavior.
Feeding and Diet
Bloodfin Tetras have an unfussy palate and accept a variety of dried, frozen, and live foods. Offering a high-quality diet of live and frozen foods will condition them for successful breeding.
Reproduction & Dimorphism
To breed this species, set up a separate tank with fine-leaved plants for spawning. The females appear fuller when ready to spawn, while the males display vibrant colors. After spawning, remove the adults to prevent them from consuming the eggs. Males develop small hooks on pelvic and anal fins as they mature, distinguishing them from the slimmer females.
Habitat and Distribution
Naturally found in streams, rivers, and tributaries shaded by floating or overhanging vegetation, the Bloodfin Tetra is endemic to the Paraná River drainage in Brazil, Paraguay, and Argentina. Its native habitat influences its preference for densely planted aquariums with areas for swimming and floating vegetation.
