Buenos Aires Tetra - Hyphessobrycon anisitsi : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Buenos Aires Tetra (Hyphessobrycon anisitsi) stands out as a relatively peaceful, resilient, and active fish species, which makes it a perfect candidate for beginner hobbyists and community aquariums. Known for their hardiness and longevity, these Tetras have no special requirements or conditions to flourish. However, it's essential to ensure they are adequately fed to reduce the chance of fin-nipping, particularly when sharing a tank with long-finned tankmates.
The social behaviour of Buenos Aires Tetras is best expressed when they are kept in schools, a setting that can further suppress any fin-nipping tendencies. However, potential owners should be aware of their propensity to consume live aquarium plants. The unique combination of Buenos Aires Tetras' size and agility makes them an ideal choice for cohabitation with territorial species such as small Central American Cichlids or Eartheaters. Acting as a beneficial target for aggression, these Tetras contribute to a harmonious aquarium environment, provided the space is ample enough for them to retreat when necessary.
Physically, Buenos Aires Tetras exhibit a silvery colour with neon highlights. Their anal and pelvic fins, along with the top and bottom of the tail fin, often display a red hue. Even their dorsal fin may carry a touch of red. Their most distinctive feature is a bold, black cross pattern found on the caudal peduncle, which significantly contributes to their appeal. An Albino variant of this species is also available, offering an additional choice for aquarists.

Sexual Dimorphism
Differentiating between male and female Buenos Aires Tetras is generally an uncomplicated task, with differences primarily manifesting in physical attributes. Females are typically characterized by a larger, fuller-bodied appearance, particularly evident in their more rounded stomach region. On the other hand, males often stand out with their more vividly coloured red fins, which in some cases may even display a slight leaning towards yellow. These distinguishing characteristics based on body shape and fin colouration facilitate the easy identification of sexes within this species.

Natural Habitat
Originating from the La Plata region of South America, the Buenos Aires Tetra is a truly captivating species. These stunning fish are indigenous to Argentina, Paraguay, and Southeastern Brazil, where they inhabit a wide range of aquatic environments. These range from slow-moving ponds and lakes to streams and two major rivers, namely the Uruguay and Parana Rivers.
As a freshwater species, Buenos Aires Tetras exhibit high sensitivity to pollution and high salinity levels in their habitat. Therefore, they thrive best in pristine, balanced aquatic environments that closely emulate their natural habitats. Whether you're an experienced aquarist or a novice in the realm of fishkeeping, the Buenos Aires Tetra is a fantastic species to consider for your aquarium. These fish offer an engaging mix of vibrant appearance and unique environmental requirements.
Breeding
Breeding Buenos Aires Tetras is a relatively straightforward process, and with no parental care required, they prove to be an ideal choice for budding aquarists. The breeding process begins with setting up a separate, dimly lit tank intended specifically for breeding. This tank should feature ample plant coverage—Java moss or an equivalent substitute is recommended—to provide locations for the female to deposit her eggs. Spawning mops can also be employed as suitable alternatives.
The water in the breeding tank should be slightly acidic, soft, and maintained at a temperature slightly higher than their regular habitat. Including a small air-powered filter in the tank, setup will facilitate gentle water movement and effective filtration.
Buenos Aires Tetras can be bred either in small groups or as pairs. For optimal results, it's advisable to select the most vibrantly coloured fish and feed them a generous portion of small live foods. Spawning typically takes place at dawn, with the females laying their eggs on the plants within the tank.
Following the egg-laying, it's crucial to promptly remove the parent fish to safeguard the eggs from potential consumption. The eggs will usually begin hatching within a span of 24 to 36 hours. Around 3 to 4 days later, the emerging fry will become free-swimming, marking the successful completion of the breeding process.
Diet & Feeding
Buenos Aires Tetras are well-known for their flexibility in terms of diet, readily consuming a variety of food types. This range includes dried, flake, and freeze-dried food options. However, to ensure these Tetras maintain their optimal health, condition, and vibrant colouration, it's recommended to supplement their diet with live foods. Suitable choices include daphnia, bloodworms, mosquito larvae, and brine shrimp.
A feeding routine involving multiple sessions per day is often beneficial for Buenos Aires Tetras. However, it's essential to remember that the portions given during each feeding session should be small. This practice not only promotes better digestion but also helps maintain a cleaner tank environment by reducing excess food waste.
