Why choose Blue Grass Guppys?

Blue Grass Guppies are recognised for their fine blue and black patterning, especially across the tail and dorsal fin. The dense, grass-like markings create a highly detailed appearance that rewards close viewing.

Their metallic blue tones become more noticeable under full-spectrum lighting and against darker backgrounds. Males are typically the most intensely patterned, while females contribute size, genetics and breeding potential.

This is a popular strain among guppy enthusiasts because it combines ornamental beauty with the hardy, active nature expected from domestic guppies.

  • Elegant flowing fins
  • Peaceful community fish
  • Hardy and easy to care for
  • Excellent display strain
  • Popular with guppy breeders

Care made simple

  • Temperature: 22–28Β°C
  • pH: 6.8–8.0
  • Diet: Premium guppy flakes or pellets, frozen foods and small live foods
  • Water: Clean, stable and well-filtered
  • Setup: Planted aquarium with open swimming areas and gentle to moderate flow
  • Perform weekly water changes to maintain excellent water quality.

NTA Insight:
The 'grass' pattern should appear fine and distributed rather than forming large solid patches. Pattern density and blue intensity vary between individuals, particularly as juvenile fish mature.

FAQ

How big do Blue Grass Guppys grow?

Most adults reach approximately 4–6 cm. Females are usually larger and fuller-bodied than males.

Are they suitable for beginners?

Yes. Guppies are generally hardy and straightforward to care for when kept in a cycled aquarium with stable water quality.

Will they breed in my aquarium?

Yes. Guppies are livebearers and will often reproduce when males and females are housed together. Dense plants can provide shelter for newborn fry.

Can they live with shrimp?

They generally coexist well with adult dwarf shrimp, although very small shrimplets may occasionally be eaten. Moss and dense planting improve shrimplet survival.

Will every fish look exactly like the photo?

No. Colour intensity, pattern placement, body shape and finnage naturally vary between individual live fish, particularly in selectively bred strains.

    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.
