{"product_id":"motoro-ray-pair-male-female-potamotrygon-motoro","title":"Motoro Ray Pair Male\/Female | Potamotrygon motoro","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Motoro, or Ocellate River Stingray, is one of the most impressive freshwater fish in the hobby, with a broad, sandy-brown disc patterned in eye-catching orange-ringed spots. This listing is for a male\/female pair. Be aware that this is a very large, long-lived and demanding animal: the disc can reach around 50 cm, it needs an enormous aquarium, and it carries a venomous tail spine, so it is strictly for experienced, well-prepared keepers.\u003c\/p\u003e\n\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\n\u003cp\u003ePotamotrygon motoro is widespread through the Amazon and other South American river basins, where it glides over sandy and silty bottoms in warm, soft, slow-moving rivers and floodplains, hunting for buried prey.\u003c\/p\u003e\n\u003ch2\u003eAppearance\u003c\/h2\u003e\n\u003cp\u003eIt has a smooth, rounded disc in shades of grey-brown to tan, decorated with numerous yellow-to-orange spots each ringed with a darker halo. The long tail bears one or more venomous serrated spines. A disc width of around 40–50 cm is typical, with a total length up to a metre.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\n\u003cp\u003eGenerally peaceful towards fish too large to be eaten, but its venomous spine makes careful handling and thoughtful stocking essential. It should share space only with large, peaceful, non-aggressive companions that will not nip at the disc or compete for the bottom.\u003c\/p\u003e\n\u003ch2\u003eFeeding\u003c\/h2\u003e\n\u003cp\u003eA carnivore with a fast metabolism. Offer meaty foods such as prawns, mussel, earthworms and pieces of fish, feeding two to three times per day for growing rays. A varied, high-quality diet is essential for long-term health.\u003c\/p\u003e\n\u003ch2\u003eCare Requirements\u003c\/h2\u003e\n\u003cp\u003eThis ray needs pristine, warm, soft water and an extremely large aquarium — at least 1,500 litres for a single adult, and more for a pair — with a wide footprint, soft sand substrate and powerful filtration. Rays are highly sensitive to nitrate and dissolved wastes, so large, frequent water changes are non-negotiable.\u003c\/p\u003e\n\u003ch2\u003eBreeding\u003c\/h2\u003e\n\u003cp\u003eRiver stingrays are livebearers, giving birth to a small number of well-developed pups after a gestation of around three months. Breeding is achievable with a compatible, well-conditioned pair in a very large system, but rearing pups demands excellent water quality and abundant food.\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\u003ePotamotrygon motoro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eMotoro Stingray, Ocellate River Stingray\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eSouth America (Amazon and other river basins)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003eAround 40–50 cm disc width\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e10–20 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful, but carries a venomous tail spine\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\u003e1,500 litres (single adult)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e2,000 litres or larger for a pair\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eCarnivore – prawn, mussel, earthworm, fish pieces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e24–28 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e6.0–7.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003e2–12 dGH (soft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003eNot applicable (freshwater)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eVery large, specialist 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\u003eNot typically planted – requires open sand substrate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\n\u003cp\u003eLarge, peaceful South American fish such as bigger peaceful cichlids, silver dollars, large tetras and robust catfish that stay off the sand bed.\u003c\/p\u003e\n\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\n\u003cp\u003eAggressive or fin-nipping fish, bottom-dwelling species that compete for the substrate, small fish that will be eaten, and anything requiring hard, alkaline water.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55232885096739,"sku":"AA2198-S","price":435.0,"currency_code":"AUD","in_stock":false},{"title":"Medium (5-10cm)","offer_id":55232885129507,"sku":"AA2198","price":499.0,"currency_code":"AUD","in_stock":false},{"title":"Large (10-15cm)","offer_id":55232885162275,"sku":"AA2198-L","price":575.0,"currency_code":"AUD","in_stock":false},{"title":"X-Large (15-50cm)","offer_id":55351970955555,"sku":"AA2198-XL","price":660.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/motoro-ray-pair-male-female-43091601031459.webp?v=1790304132","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/motoro-ray-pair-male-female-potamotrygon-motoro","provider":"Nicks AOT","version":"1.0","type":"link"}
