{"product_id":"bariene-tang","title":"Bariene Tang | Acanthurus bariene","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Bariene Tang (Black-Spot or Orange-Face Tang) is a handsome, large-growing surgeonfish with an orange face mask and a distinctive dark spot near the tail. It is active and personable but becomes a big fish, so it needs a large, established aquarium with plenty of open swimming room and strong water movement.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eIn the wild, the Bariene Tang is associated with clear outer reef slopes and deeper coastal reefs of the Indo-Pacific. It ranges widely, grazing algae from rock and reef surfaces throughout the day. Replicating this environment means providing mature live rock with algae films for grazing, generous open swimming lanes and strong, well-oxygenated flow. A newly set-up aquarium is rarely ideal, as this fish does best in a large, stable system with established grazing surfaces.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eThe Bariene Tang has a deep, oval body, an orange facial mask with fine markings around the eyes, and a black spot near the tail base. Colour and pattern intensify in a healthy, well-fed adult. This is a large tang that reaches around 40–50 cm, so its adult size and swimming needs must be planned for before purchase. Like all surgeonfish it carries a sharp scalpel near the tail base. Healthy specimens are alert, well-filled and grazing actively, without pinched bellies, cloudy eyes or rapid breathing.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eTemperament is best described as semi-aggressive, particularly towards other tangs and fish of similar shape. In a large aquarium it can be a good community fish with dissimilar species. Suitable companions include clownfish, wrasses, angels, rabbitfish, chromis and other robust reef fish. Housing it with other tangs is best attempted only in very large systems with careful planning. Add it to a settled aquarium and avoid combinations that lead to constant chasing.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eFeeding should be predominantly herbivorous. Offer dried marine algae and nori on a clip, algae-based flakes and pellets, and a rotation of prepared herbivore foods, ideally several small feeds through the day. Occasional meaty foods such as mysis shrimp can be offered, but the diet should remain mostly plant based. A well-fed tang holds its colour and body condition and is less likely to graze on corals.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eFor long-term success, provide a minimum aquarium size of 750 L, with 1100 L or larger strongly recommended given the adult size and activity level. A long tank with generous open swimming room suits this species. Maintain temperature at 24–26°C, pH 8.1–8.4 and salinity around 1.020–1.026. Strong, well-oxygenated flow is important. Lighting can be standard reef lighting. Provide open lanes and mature live rock for grazing. Strong filtration, a large protein skimmer and regular water changes of 10–20% are important. Surgeonfish are prone to white spot, so stable water quality and a quarantine routine are advised. This species is considered reef safe.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eBreeding in the home aquarium is not achieved and should not be expected. In nature, surgeonfish spawn in open water, releasing eggs and sperm into the current, with larvae drifting as plankton before settling. This requires specialised conditions far beyond normal home aquarium keeping. For hobbyists, the focus should be on long-term health, correct herbivorous feeding, excellent water quality and low stress.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eAcanthurus bariene\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eBariene Tang (Black-Spot \/ Orange-Face Tang)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eIndo-Pacific outer reef slopes and deeper coastal reefs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e40–50 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003eOften 10 years or more with excellent care\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003eSemi-aggressive, especially to other tangs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eIntermediate to advanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e750 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e1100 L or larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eHerbivore; marine algae, nori and algae-based prepared foods\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, established reef and fish-only systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eReef safe\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 clownfish, wrasses, angels, rabbitfish, chromis and other robust reef fish that differ in shape and colour, in a large aquarium with generous swimming room.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eAvoid keeping with other tangs except in very large systems, highly aggressive fish that will harass it, and avoid adding it to small or newly set-up tanks.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55234150465827,"sku":null,"price":65.0,"currency_code":"AUD","in_stock":false},{"title":"Medium (5-10cm)","offer_id":55234150498595,"sku":"BA9250","price":75.0,"currency_code":"AUD","in_stock":true},{"title":"Large (10-15cm)","offer_id":55234150531363,"sku":null,"price":85.0,"currency_code":"AUD","in_stock":false},{"title":"X-Large (15-40cm)","offer_id":55351952179491,"sku":null,"price":95.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/Bariene_Tang_Acanthurus_bariene_2291e438-0901-4548-83b3-50141259c9aa.jpg?v=1781681465","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/bariene-tang","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
