Dwarf Rasbora (Boraras maculatus)

One of the smallest freshwater fish in the world, the Dwarf Rasbora is a tiny jewel with glowing ruby-red colours and a peaceful personality that's perfect for nano aquariums and shrimp tanks.

Quick Facts

  • Adult size: 2–2.5 cm
  • Tank size: 20L+ recommended
  • Difficulty: 🟢 Easy
  • Temperament: Extremely peaceful
  • Best kept: Schools of 10 or more

Is this for you?

✔️ Perfect if:

  • You love nano aquariums.
  • You keep shrimp or planted aquascapes.
  • You enjoy tiny schooling fish.
  • You want a peaceful community aquarium.

❌ Avoid if:

  • You keep large or boisterous fish.
  • Your aquarium has strong water flow.

Why choose Dwarf Rasboras?

Despite their tiny size, Dwarf Rasboras are packed with colour and personality. Mature fish develop beautiful ruby-red bodies accented by distinctive dark spots, creating an elegant display as they school through lush aquatic plants.

Their small size makes them ideal for nano aquariums where larger fish would overwhelm the aquascape. They spend much of their day gently weaving through mosses, stem plants and driftwood while constantly foraging for tiny food items.

When kept in large groups, these little fish become surprisingly confident and create an impressive cloud of colour that perfectly complements shrimp and planted aquariums.

NTA Insight:
Dwarf Rasboras are often overlooked because of their size, but they're one of the best fish you can add to a true nano aquarium. Once settled into a mature planted tank with dark substrate and floating plants, their red colours intensify dramatically. We recommend keeping at least 12–20 together—the larger the school, the more confident and visible they become.

FAQ

How many Dwarf Rasboras should I keep?

Although six is considered the minimum, we strongly recommend keeping at least 10–12 fish. Larger schools display better colour, tighter schooling behaviour and much greater confidence.

Are Dwarf Rasboras peaceful?

Yes. They are among the most peaceful freshwater fish available and are ideal for nano community aquariums.

Can they live with shrimp?

Absolutely. They are one of the safest fish for shrimp tanks. While they may occasionally eat newly hatched shrimplets, healthy shrimp colonies with plenty of moss and cover usually thrive alongside them.

Can Dwarf Rasboras breed in home aquariums?

Yes. In mature planted aquariums they may spawn naturally, scattering tiny eggs among fine-leaved plants and mosses. A dedicated breeding setup greatly increases fry survival.

Why are my Dwarf Rasboras pale?

New fish often appear washed out after transport. Given stable water, quality food, subdued lighting and a planted aquarium, they usually develop much richer red colouration within a few weeks.

    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.
