Description

Serpae Tetra 2-4cm

Serpae Tetra brings schooling movement with a clearly named colour or pattern to a suitably prepared aquarium. Plan its home around adult space, water, diet and social needs rather than the current sale size.

Quick Facts

  • Product type: schooling freshwater fish
  • Sale size: Approximately 2–4cm as listed
  • Sale unit: One individual per quantity ordered unless the listing states otherwise
  • Social needs: Social fish generally best kept in an appropriate group; fin-nipping potential varies by species

Is this for you?

Perfect if: you can keep an appropriate group and choose companions suited to this tetra’s adult size and activity.

Consider something else if: you want a solitary fish or have predatory, very timid or incompatible long-finned companions.

Why choose Serpae Tetra?

Choose Serpae Tetra for schooling movement with a clearly named colour or pattern. Base compatibility and long-term housing on its adult requirements; individual appearance and maturity can vary.

Key Benefits

  • Schooling movement with a clearly named colour or pattern
  • Husbandry guidance focused on schooling freshwater fish needs
  • Clear sale-size and sale-unit information for purchase planning

Care & Specifications

Use a mature, covered aquarium with open schooling space, planting or wood for security and stable water. Match temperature and chemistry to the exact tetra.

Social requirements: Social fish generally best kept in an appropriate group; fin-nipping potential varies by species.

What will you receive?

You will receive the selected quantity of Serpae Tetra 2-4cm. Size within the stated range, colour, markings, finnage and sex can vary between individuals unless the listing explicitly fixes them.

Acclimation & Introduction

Prepare the schooling freshwater fish aquarium before arrival and follow current NTA livestock acclimation guidance. Reduce lighting, avoid sudden changes in temperature or water chemistry, and monitor breathing, posture, feeding and interactions after introduction.

Ongoing Care

Offer fine flakes or micro-pellets with suitable frozen foods. Spread small portions so subordinate fish can feed.

Maintain stable water through testing and appropriately sized water changes. Review the setup as Serpae Tetra grows or social behaviour changes.

Pairs perfectly with

  • A mature aquarium prepared for this livestock
  • Reliable water tests and species-appropriate filtration
  • Food selected for the animal’s mouth size and feeding zone
NTA Insight:
A larger group often looks better and spreads social pressure, but it does not fix insufficient swimming space or unsuitable tank mates.

Before You Buy

Check the adult size, social structure, water requirements and diet for Serpae Tetra before ordering. The listed sale size describes current stock, not its permanent size.

Compatibility lists are guides only. Individual behaviour, aquarium dimensions, sex, group size and established territories can change the outcome.

FAQ

Can I keep a single tetra?
Tetras are social fish and are generally better kept in an appropriate group for the exact species.

Will the supplied Serpae Tetra match the photograph exactly?
No. Livestock photographs represent the species or variety; colour, markings, finnage, size and maturity naturally vary.

Is the listed size the adult size?
No. It is an approximate sale size where stated. Confirm adult requirements before purchase.

    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.
