Why choose Pseudomugil ivantsoffi?

Pseudomugil ivantsoffi is one of the rarer members of the Blue Eye Rainbowfish family and is highly prized by enthusiasts of Australian and Papua New Guinea rainbowfish. Mature males develop elegant yellow to golden fins that contrast beautifully with their unmistakable sapphire-blue eyes.

Like other Blue Eyes, males regularly display to one another by extending their fins and performing gentle courtship dances. These interactions are peaceful and become increasingly impressive as the group matures.

When housed in a densely planted aquarium with dark substrate and quality lighting, their colours intensify dramatically, creating an elegant and constantly active display.

Common mistakes

  • Keeping too few fish.
  • Housing them with aggressive or boisterous species.
  • Leaving the aquarium uncovered—they are capable jumpers.
  • Providing little plant cover.
  • Allowing water quality to deteriorate.

Care made simple

  • Temperature: 22–28°C
  • pH: 6.5–7.8
  • Diet: Premium nano pellets, baby brine shrimp, daphnia, microworms and frozen foods
  • Water: Clean, stable and well-filtered with gentle flow
  • Setup: Heavily planted aquarium with floating plants, open swimming areas and a secure lid

Pairs perfectly with

  • Pseudomugil luminatus
  • Pseudomugil gertrudae
  • Threadfin Rainbowfish
  • Corydoras
  • Java Moss and fine-leaved aquatic plants
NTA Insight:
Pseudomugil ivantsoffi isn't seen nearly as often as Luminatus or Gertrudae, making it a fantastic choice for hobbyists looking for something a little different. Their peaceful nature, striking blue eyes and elegant yellow finnage make them a rewarding species that really shines when kept in a large school.

FAQ

How many Pseudomugil ivantsoffi should I keep?

Keep them in groups of at least eight individuals. Larger schools encourage more natural behaviour, stronger colours 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 protection for young shrimp.

Are they suitable for beginners?

They are relatively easy to care for once established, but their rarity means they're often chosen by hobbyists looking to expand their Blue Eye collection.

Can they breed in home aquariums?

Yes. Like other Blue Eye Rainbowfish, they spawn readily among fine-leaved plants or spawning mops when maintained in excellent water quality.

What makes Pseudomugil ivantsoffi special?

Its rarity, brilliant sapphire-blue eyes and elegant golden-yellow finnage make it one of the more unusual and desirable members of the Pseudomugil genus.

    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.
