{"product_id":"spotted-blue-eye-pseudomugil-gertrudae","title":"Spotted Blue Eye | Pseudomugil gertrudae","description":"\u003ch2\u003eDescription\u003c\/h2\u003e \u003cp\u003eThe Spotted Blue-Eye is a tiny living gem — a slender body peppered with dark spots, glowing blue eyes and delicate, yellow-and-black edged fins that the males flick and flare in constant display. Staying just 3–4 cm, this peaceful nano shoaler dazzles in a soft, planted tank and is a favourite for the nature aquarium.\u003c\/p\u003e \u003ch2\u003eNatural Habitat\u003c\/h2\u003e \u003cp\u003ePseudomugil gertrudae is native to northern Australia, southern New Guinea and nearby islands, where it lives in soft, often tannin-stained rainforest streams, swamps and lily lagoons among dense vegetation. The water is typically warm, acidic and gently flowing.\u003c\/p\u003e \u003ch2\u003eAppearance\u003c\/h2\u003e \u003cp\u003eA small, semi-transparent rainbowfish relative with a rounded body dotted in fine dark spots, luminous blue eyes and twin dorsal fins. Males are the showstoppers, raising large, spotted, yellow-edged fins in near-constant \"sparring\" displays, while females are plainer and slightly smaller.\u003c\/p\u003e \u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e \u003cp\u003eCompletely peaceful and best kept in a good-sized group of eight or more, ideally with several males so their displays are on show. It suits a calm nano community, but its small size means tank mates must be equally small and gentle — it can be shy or out-competed among boisterous fish.\u003c\/p\u003e \u003ch2\u003eFeeding\u003c\/h2\u003e \u003cp\u003eA micro-predator with a tiny mouth. Offer small, high-quality flake, crushed micro-pellets and, importantly, plenty of small live and frozen foods such as daphnia, cyclops, baby brine shrimp and micro-worm to keep condition and colour up.\u003c\/p\u003e \u003ch2\u003eCare Requirements\u003c\/h2\u003e \u003cp\u003eProvide a well-planted aquarium of at least 20 L, ideally 40 L or more, with gentle filtration. Keep the temperature at 23–28 °C, pH 5.5–7.5 (it prefers the softer, more acidic end) and soft to moderately soft water. Dense planting, some floating cover and a lid suit it well. Note this is a short-lived species, often living only 1–2 years even with good care. It is plant safe.\u003c\/p\u003e \u003ch2\u003eBreeding\u003c\/h2\u003e \u003cp\u003eA continuous egg-scatterer that deposits eggs among fine-leaved plants and spawning mops over many days. The adults do not care for the eggs and may eat them, so mops or plants are best moved to a separate container to hatch. The fry are tiny and need infusoria-grade first foods.\u003c\/p\u003e \u003ch2\u003eSpecies Information\u003c\/h2\u003e \u003ctable\u003e \u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003ePseudomugil gertrudae\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eSpotted Blue-Eye, Gertrude's Blue-Eye\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eNorthern Australia, southern New Guinea and nearby islands\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003eAround 3–4 cm\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e1–2 years (naturally short-lived)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful (schooling)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eIntermediate\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e20 L\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e40 L or larger, planted\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eMicropredator: small flake, micro-pellets, live and frozen foods\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e23–28 °C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e5.5–7.5\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003eSoft to moderately soft, around 2–12 dGH\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003eNot applicable (freshwater)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eSoft-water planted nano aquariums\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e \u003c\/table\u003e \u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e \u003cp\u003eSuitable tank mates include other small blue-eyes, chili and dwarf rasboras, pygmy corydoras, otocinclus and dwarf shrimp in a peaceful planted tank.\u003c\/p\u003e \u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e \u003cp\u003eAvoid keeping with larger, boisterous or predatory fish, fin-nippers, and anything big enough to eat or out-compete this tiny species.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55232828997923,"sku":"AA1520","price":18.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/spotted-blue-eye-pseudomugil-43091533529379.webp?v=1790306577","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/spotted-blue-eye-pseudomugil-gertrudae","provider":"Nicks AOT","version":"1.0","type":"link"}
