Buenos Aires Tetra 3cm

Description

Buenos Aires Tetra (Hyphessobrycon anisitsi)

Fast, hardy and full of colour, the Buenos Aires Tetra is a robust South American schooling fish with a silver body, green-gold sheen and vivid red-orange fins. It is an excellent choice for aquarists wanting an active, highly visible tetra, but its boisterous nature means tankmates should be chosen with a little more care than for gentler community tetras.

Is this for you?

βœ”οΈ Perfect if:

  • You want a hardy, active schooling tetra.
  • You prefer fish with strong red-orange fin colour.
  • You have a medium to large community aquarium.
  • You want a species tolerant of a reasonably broad temperature range.
  • You can keep them in a proper group to spread normal chasing behaviour.

❌ Avoid if:

  • You keep slow-moving or long-finned fish such as fancy guppies or long-finned bettas.
  • You want a very calm nano-community species.
  • Your aquarium is heavily planted with delicate plants you do not want grazed.
  • You plan to keep only one or two individuals.

Why choose Buenos Aires Tetras?

Buenos Aires Tetras are one of the hardier and more energetic members of the tetra group. Their metallic silver-green body and bright red fins make them easy to spot even in a busy community aquarium.

They are confident feeders, adapt well to a range of water conditions and generally settle quickly when kept in a good-sized school.

The trade-off is that they are more boisterous than many smaller tetras. Keeping them in a proper group and avoiding very slow or long-finned tankmates greatly reduces nuisance fin-nipping.

Benefits

  • Very hardy and adaptable
  • Strong red-orange fin colour
  • Active schooling behaviour
  • Easy to feed
  • Good visibility in larger aquariums
  • Suitable for cooler tropical setups
  • Excellent choice for robust community aquariums

Care made simple

  • Temperature: Approximately 18–26Β°C
  • pH: Approximately 6.0–8.0
  • Water: Clean, stable and well oxygenated
  • Diet: Omnivorous
  • Staple foods: Quality flakes and suitably sized pellets
  • Supplement with: Brine shrimp, daphnia, bloodworms and other varied frozen or live foods
  • Flow: Gentle to moderate
  • Setup: Open swimming space with sturdy plants around the sides and rear
  • Keep in a group of at least six to promote natural behaviour.
  • Monitor compatibility with slow-moving or long-finned tankmates.

Pairs perfectly with

  • Other robust tetras
  • Barbs of similar temperament
  • Corydoras
  • Rainbowfish
  • Danios
  • Other active community fish of similar size
NTA Insight:
Buenos Aires Tetras are best treated as a robust community fish rather than a delicate peaceful tetra. A larger group spreads chasing behaviour, while plenty of open swimming room helps them burn off energy. They may also nibble softer aquarium plants, so tougher species such as Anubias, Java Fern and similar sturdy plants are safer choices.

Adults commonly reach around 6–7 cm.

How many should I keep?

    Live Arrival & Ordering FAQ

    Why do livestock prices sometimes change?

    Unlike manufactured products, fish and shrimp continue to grow and develop over time. Their value changes as they increase in size, develop colour, or become breeding pairs.

    Our prices are based on the current size, quality and availability of each specimen. While pricing often remains stable for around 3–4 months, it may be updated at any time to reflect these changes.

    We always aim to offer healthy, high-quality livestock at fair and competitive prices.

    Do you offer a live arrival guarantee?

    Yes. All livestock is covered by our Live Arrival Guarantee.

    In the rare event of DOA, please contact us promptly with clear photos of the livestock in the original unopened bag.

    Please review our full DOA and store policies before purchase.

    Can you ship to all states in Australia?

    No. Due to state restrictions, we cannot ship livestock or live plants to WA and TAS.

    What should I check before ordering?

    Before placing an order, make sure:

    • Your tank is fully cycled and stable
    • Your aquarium has enough space for the species
    • Your current livestock are compatible in temperament, size, and requirements
    • Your water parameters, habitat, and temperature suit the species
    • You are not adding too many fish at once
    What should I expect when my fish arrives?

    It is normal for fish, shrimp, or snails to look pale, stressed, or less active after shipping.

    This is temporary. Most livestock will settle and regain colour within a few days.

    How long does it take for fish to settle in?

    Most livestock will take 3–7 days to fully adjust to their new environment.

    Should I feed my fish immediately after arrival?

    No. We recommend waiting 24 hours before feeding to allow them to settle.

    If you already have fish in your tank, feeding them before introducing new arrivals can help reduce stress.

    Why do fish sometimes struggle after being added to a tank?

    In most cases, issues are caused by tank conditions, not shipping.

    • Uncycled or unstable tanks
    • Poor water parameters
    • Overstocking
    • Unsuitable tank mates
    What is Nano Tanks Australia’s main tip for new livestock?

    Most livestock losses happen in immature or unstable tanks, not during shipping.

    If your setup is not fully established, the risk to new arrivals is significantly higher.

    Not sure if this fish is right for your setup?

    If you are unsure whether this species suits your setup, contact us before ordering and we’ll help point you in the right direction.
