It is an unusual and rewarding fish for a small biotope or hard-water nano tank, and appreciates a touch of salt. As a small, specialised micropredator it suits an aquarist happy to offer small live and frozen foods.\u003c\/p\u003e\n\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\n\u003cp\u003eThis goby is found in the estuaries, tidal creeks and mangrove margins of northern Australia, over sandy mud among mangrove roots, logs and leaf litter. It lives where fresh and salt water meet, tolerating a wide range from low-salinity brackish to hard fresh water.\u003c\/p\u003e\n\u003ch2\u003eAppearance\u003c\/h2\u003e\n\u003cp\u003eA small, stocky goby reaching only around 3–4 cm, with a rounded, snub-nosed head and fused pelvic fins that form a little suction disc typical of gobies. The body is sandy-brown with a row of darker blotches along the flank and fine scale markings, providing excellent camouflage over mud and sand.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\n\u003cp\u003ePeaceful towards other species but males will defend small territories on the bottom, especially around caves or shells. It is a micropredator best kept with small, calm tankmates that share its preference for harder or slightly brackish water, and it should not be housed with anything large enough to eat it.\u003c\/p\u003e\n\u003ch2\u003eFeeding\u003c\/h2\u003e\n\u003cp\u003eA micro-carnivore that often ignores dry flake. Offer small live and frozen foods such as brine shrimp, daphnia, bloodworm and micro pellets aimed at the bottom. Target-feeding helps ensure this small, deliberate feeder gets its share.\u003c\/p\u003e\n\u003ch2\u003eCare Requirements\u003c\/h2\u003e\n\u003cp\u003eProvide a mature tank with a soft sand bed, plenty of caves, shells or driftwood, and hard, neutral-to-alkaline water. It does well in slightly brackish set-ups but adapts to hard fresh water. Gentle filtration, stable conditions and a secure lid suit it. Because it is a specialised feeder, it is best considered an intermediate species.\u003c\/p\u003e\n\u003ch2\u003eBreeding\u003c\/h2\u003e\n\u003cp\u003eLike many gobies, it is a cave or shell spawner. The male guards a clutch of eggs laid on the roof of a cave or shell until they hatch. Rearing the tiny fry is challenging and generally benefits from brackish conditions and very small live foods.\u003c\/p\u003e\n\u003ch2\u003eSpecies Information\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003ePseudogobius aquilonius\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eNorthern Snubnose Goby\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eNorthern Australia (estuaries and mangroves)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003eAround 3–4 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e2–3 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful; males mildly territorial on the bottom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eIntermediate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e40 litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e60 litres or larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eMicro-carnivore – small live and frozen foods\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e20–28 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e7.0–8.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003e8–20 dGH (hard)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003eFreshwater to low brackish – tolerates a little salt (up to about SG 1.005)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eHard-water nano and brackish biotope aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eYes – harmless to plants (though brackish set-ups limit plant choice)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\n\u003cp\u003eOther small, peaceful hard-water or brackish-tolerant fish, such as Pacific blue-eyes, small rainbowfish, other small gobies and shrimp that can handle the same conditions.\u003c\/p\u003e\n\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\n\u003cp\u003eLarge or aggressive fish, anything big enough to eat a 3 cm goby, and soft, acidic-water community species that will not thrive in the hard or slightly brackish water this goby prefers.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55232771850531,"sku":"BA9283","price":17.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/northern-snubnose-goby-pseud-43878711099683.webp?v=1790305551","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/northern-snubnose-goby-pseudogobius-aquilonius","provider":"Nicks AOT","version":"1.0","type":"link"}
