{"product_id":"ring-tail-tang-xxl","title":"Ring Tail Tang XXL | Acanthurus blochii","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Ring Tail Tang is a large, powerful surgeonfish that brings constant motion and grazing to a big reef or FOWLR system. This is an XXL specimen, and the species reaches around 45 cm, so it demands a very large aquarium with plenty of open swimming room. It is a rewarding but demanding fish for the experienced keeper.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eWidespread across the Indo-Pacific, from East Africa to Hawaii, where adults roam shallow reef flats and lagoon edges grazing algae, often in loose groups.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eA robust, oval-bodied tang in shades of blue-grey to bronze, finely stippled, with a pale ring or bar at the base of the tail that gives it its name and yellow around the eyes and pectoral base.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eSemi-aggressive, particularly toward other tangs and surgeonfish and especially in confined space. In a large enough system it mixes with a wide range of robust community fish. Introduce other tangs together or add this one last.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003ePrimarily a herbivore. Provide dried marine algae (nori) daily along with Spirulina-based prepared foods and some enriched meaty foods, and allow natural algae grazing. Steady feeding helps prevent aggression and maintains condition.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eRequires a very large aquarium of at least 750 litres, ideally 1,000 litres or more for an adult of this size, with strong flow, high oxygenation and open swimming lanes. Maintain 24–26 °C, pH 8.1–8.4 and salinity 1.020–1.026. Tangs are prone to whitespot, so stable conditions and good nutrition are key.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eNot bred in home aquaria. Surgeonfish are pelagic spawners with a long larval stage that has not been reared commercially.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eAcanthurus blochii\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eRing Tail Tang (Ringtail Surgeonfish)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eIndo-Pacific\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e45 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e15+ years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003eSemi-aggressive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eAdvanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e750 litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e1,000 litres or larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eHerbivore\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e24–26 °C\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\u003eLarge reef or FOWLR aquarium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eGrazes on algae; may nip macroalgae\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eRobust reef and FOWLR fish in a large system — larger angelfish, other tangs (added together), wrasses, groupers, and other fish that can hold their own.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eAvoid keeping with other Acanthurus tangs in cramped tanks, and with very small, timid fish that may be intimidated by its bulk and activity.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm) \/ Australian Caught","offer_id":55234139029795,"sku":"AA5003-S","price":185.0,"currency_code":"AUD","in_stock":false},{"title":"Medium (5-10cm) \/ Australian Caught","offer_id":55234139062563,"sku":"AA5003-M","price":215.0,"currency_code":"AUD","in_stock":false},{"title":"Large (10-15cm) \/ Australian Caught","offer_id":55234139095331,"sku":"AA5003-L","price":245.0,"currency_code":"AUD","in_stock":false},{"title":"X-Large (15-45cm) \/ Australian Caught","offer_id":55351941300515,"sku":"AA5003-XL","price":280.0,"currency_code":"AUD","in_stock":false},{"title":"Small (1-5cm) \/ Imported","offer_id":55562730111267,"sku":"AA5003-S-IMP","price":185.0,"currency_code":"AUD","in_stock":false},{"title":"Medium (5-10cm) \/ Imported","offer_id":55562730144035,"sku":"AA5003-M-IMP","price":215.0,"currency_code":"AUD","in_stock":false},{"title":"Large (10-15cm) \/ Imported","offer_id":55562730176803,"sku":"AA5003-L-IMP","price":245.0,"currency_code":"AUD","in_stock":false},{"title":"X-Large (15-45cm) \/ Imported","offer_id":55562730209571,"sku":"AA5003-XL-IMP","price":280.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/ring-tail-tang-xxl-43090655969571.webp?v=1790306148","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/ring-tail-tang-xxl","provider":"Nicks AOT","version":"1.0","type":"link"}
