{"product_id":"krefft-s-frillgoby","title":"Krefft's Frillgoby | Bathygobius krefftii","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eKrefft's Frillgoby is a hardy, characterful little Australian goby with a dark, spotted body and a habit of perching boldly on rocks. Native to estuaries and rocky shores along the east coast, it is an adaptable, undemanding fish that suits a cooler-water marine or estuarine-style aquarium. It stays small at around 9–12 cm and has plenty of personality for its size.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eThis species is common near the mouths of estuaries and along rocky shores of eastern Australia, from New South Wales to southern Queensland, with an isolated population in South Australia. It favours shallow seagrass beds, oyster beds and rocky estuarine areas, sheltering in crevices and among rubble. It comes from temperate to subtropical water, so it prefers cooler conditions than a tropical reef fish. In the aquarium it needs rockwork with hiding spots and a sand or rubble bottom.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eThe body is dark brown to blackish, marked with scattered small brown spots on the cheeks and gill covers, a broad dark bar below the first dorsal fin, and rows of white spots forming faint lines along the flanks. The frilly pectoral and dorsal fins give the \"frillgoby\" name. Healthy specimens perch alertly, are quick to dart for food, and show clear eyes and undamaged fins.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eKrefft's Frillgoby is generally peaceful but can be territorial around its chosen perch or crevice, especially with other bottom-dwellers. It suits a calm system with other temperate-tolerant fish. It will not bother corals, though it may eat very small shrimp. Provide enough rockwork so each bottom-dweller can claim its own patch and reduce squabbling.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eThis is a benthic carnivore that feeds on small invertebrates. Offer frozen mysis, enriched brine shrimp, finely chopped prawn and other small meaty foods, along with sinking pellets. Feed once or twice daily. It is an eager, uncomplicated feeder that adapts readily to prepared foods.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eProvide a minimum aquarium of 75 L, with 100 L or larger recommended. This is a temperate to subtropical species, so aim for cooler water around 18–24°C rather than tropical reef temperatures; pH 8.1–8.4 and salinity around 1.020–1.026. Provide rockwork with crevices, a sand or rubble bottom and gentle to moderate flow. It is hardy and tolerant, making it a good choice for a cooler-water setup.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eKrefft's Frillgoby is a substrate spawner that lays eggs in a sheltered crevice, guarded by the male. While spawning can occur in a suitable aquarium, rearing the small larvae requires specialised planktonic feeding, so successful captive breeding is uncommon in the general hobby.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eBathygobius krefftii\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eKrefft's Frillgoby\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eEastern Australian estuaries and rocky shores\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003eUp to 9 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e3–5 years with good care\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful (can be territorial with bottom-dwellers)\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\u003e75 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e100 L or larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eCarnivore; small meaty frozen foods and sinking pellets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e18–24°C (temperate to subtropical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e8.1–8.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003eNot applicable for marine fish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003e1.020–1.026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eCooler-water marine and temperate species aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eYes (may eat very small shrimp)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eSuitable tank mates include other peaceful gobies, small temperate-tolerant fish and calm community species that will not outcompete it at feeding time.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eAvoid keeping with aggressive or boisterous fish, large predators, and very small ornamental shrimp that may be eaten.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm) \/ Australian Caught","offer_id":55234149810467,"sku":"BA8796-S","price":35.0,"currency_code":"AUD","in_stock":false},{"title":"Medium (5-10cm) \/ Australian Caught","offer_id":55234149843235,"sku":"BA8796","price":40.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/krefft-s-frillgoby-43090650202403.webp?v=1790306135","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/krefft-s-frillgoby","provider":"Nicks AOT","version":"1.0","type":"link"}
