Why choose Dumbo Mosaic Guppies?

The Dumbo Mosaic Guppy is one of the most elegant guppy varieties available today. Its signature oversized "Dumbo" (Elephant Ear) pectoral fins gently fan through the water, giving the impression that the fish is floating effortlessly through the aquarium.

Complementing these impressive fins is the spectacular mosaic tail, featuring intricate lace-like markings in vibrant shades of blue, black, red and iridescent metallic tones. Every fish develops its own unique pattern, ensuring no two individuals are ever identical.

Despite their premium appearance, Dumbo Mosaic Guppies remain hardy, active and easy to care for, making them suitable for both first-time aquarists and experienced breeders seeking an exceptional bloodline.

  • Beautiful mosaic-patterned tail
  • Premium selectively bred guppy strain
  • Peaceful and beginner friendly
  • Excellent for planted aquariums
  • Ideal for selective breeding projects

Care made simple

  • Temperature: 22–28°C
  • pH: 7.0–8.0
  • Diet: Quality micro pellets, flakes, live and frozen foods including brine shrimp, daphnia and bloodworms
  • Water: Clean, stable and well-filtered with gentle water movement
  • Setup: Planted aquarium with floating plants, open swimming space and minimal current
  • If keeping mixed sexes, maintain approximately one male to two or three females.
  • Regular water changes and a varied diet help maximise finnage, colour and overall health.

NTA Insight:
The oversized Dumbo fins are the defining feature of this strain and are best displayed in aquariums with gentle water movement. A dark substrate, lush green plants and quality LED lighting create a beautiful contrast that highlights both the flowing fins and intricate mosaic tail pattern. For breeding, floating plants or Java Moss provide excellent shelter for newborn fry.

    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.
