Why choose Balloon Lampeye Tetras?

The Balloon Lampeye Tetra combines the striking ruby-red eyes and metallic silver body of the standard Lampeye Tetra with a distinctive rounded body shape that gives the fish a unique appearance. Their compact profile creates a different silhouette while maintaining the same peaceful temperament and active schooling behaviour.

Native to the rivers of South America through their standard lineage, Balloon Lampeye Tetras thrive in well-maintained planted aquariums where they can swim comfortably among open areas and dense vegetation. Their reflective scales shimmer beautifully as schools move together through the aquarium.

Although slightly slower than the standard form due to their deeper body shape, they remain social, confident fish that are happiest when kept in groups.

  • Brilliant ruby-red eyes
  • Beautiful metallic silver colouration

  • Temperature: 22–28°C

  • Water: Clean, stable and well-filtered with gentle to moderate water movement
  • Setup: Spacious planted aquarium with driftwood, open swimming areas and dense planting around the edges
  • Keep in schools of at least 8 fish to encourage natural behaviour and reduce stress.

Pairs perfectly with

  • Corydoras sterbai
  • Black Neon Tetras
  • Glowlight Tetras
  • Honey Gouramis
  • Bristlenose Plecos
NTA Insight:
Balloon Lampeye Tetras look particularly attractive in mature planted aquariums with dark substrates and natural driftwood. Their rounded bodies reflect light differently from the standard variety, while their brilliant ruby-red eyes remain the defining feature. A school of 10 or more creates a lively yet elegant display that adds both movement and personality to the aquarium.

    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.
