Why choose Pseudomugil gertrudae?

Gertrude's Spotted Blue Eye is widely regarded as one of the most attractive members of the Blue Eye Rainbowfish family. Mature males develop beautifully elongated fins covered in distinctive black spotting, perfectly complemented by their striking electric-blue eyes.

Constantly active but completely peaceful, they spend their day schooling through planted aquariums while males display to one another with extended fins and graceful courtship dances.

Their combination of intricate finnage, bright eyes and shimmering golden body makes them a true centrepiece in any planted nano aquarium.

Common mistakes

  • Keeping too few fish.
  • Housing them with aggressive or fin-nipping species.
  • Using an uncovered aquarium—they are excellent jumpers.
  • Providing too little plant cover.
  • Allowing water quality to decline.

Care made simple

  • Temperature: 22–28°C
  • pH: 6.0–7.5
  • Diet: Premium nano pellets, baby brine shrimp, microworms, daphnia and frozen foods
  • Water: Clean, stable and well-filtered with gentle flow
  • Setup: Heavily planted aquarium with floating plants, open swimming space and a secure lid

Pairs perfectly with

  • Pseudomugil luminatus
  • Pseudomugil tenellus
  • Threadfin Rainbowfish
  • Corydoras
  • Java Moss and fine-leaved aquatic plants
NTA Insight:
If we had to recommend just one Blue Eye species based purely on appearance, Gertrude's Spotted Blue Eye would be near the top of the list. The intricate black spotting across the fins is unlike any other Pseudomugil species, and when a group of mature males displays together, they create one of the most spectacular sights in the nano fish hobby.

FAQ

How many Pseudomugil gertrudae should I keep?

They should be kept in schools of at least eight individuals. Larger groups produce better colours, more confident behaviour and more frequent display activity.

Can they live with shrimp?

Yes. Adult shrimp are generally safe, although tiny shrimplets may occasionally be eaten. Dense mosses provide excellent shelter for young shrimp.

Are they suitable for beginners?

Yes. Gertrude's Spotted Blue Eyes are hardy, peaceful and relatively easy to care for, making them an excellent choice for planted community aquariums.

Can they breed in home aquariums?

Absolutely. They readily spawn amongst fine-leaved plants and spawning mops, with eggs being laid individually over an extended period.

What makes Gertrude's Spotted Blue Eye different?

Their distinctive spotted fins, brilliant blue eyes and elegant display behaviour make them one of the most visually striking and sought-after Blue Eye Rainbowfish available.

    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.
