Beautiful and intelligent, they demand huge, pristine systems, careful feeding and constant respect for the venomous tail spine. With a disc reaching roughly 35–45 cm, a pair is a serious, long-term commitment for advanced keepers only.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eRiver stingrays of the genus \u003cem\u003ePotamotrygon\u003c\/em\u003e come from the slow-moving rivers, tributaries and floodplains of tropical South America, gliding over soft sand and mud where they bury themselves to ambush prey. The water is warm, soft and slightly acidic to neutral, and always clean and well-oxygenated.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eA rounded, disc-shaped ray in the \"Mantilla\" line, patterned over a brown to grey base and edged with a paler margin, sitting flat against soft sand. A venomous barb sits on the whip-like tail. Disc width reaches roughly 35–45 cm depending on line and sex.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003ePeaceful towards fish it cannot eat, but the venomous spine makes it dangerous to handle and unsuitable around children or careless maintenance. It should only share space with large, calm, non-nippy tankmates that leave it alone on the bottom.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eA carnivore that hunts along the substrate. Offer meaty foods such as earthworm, prawn, mussel, fish fillet and bloodworm, fed to the bottom. Rays have high metabolisms and need regular, generous feeding, which in turn demands heavy filtration.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eProvide a very large, low tank with a big footprint (not just volume), a soft sand bed free of sharp décor, powerful filtration and pristine, stable, soft to neutral water. Rays are extremely intolerant of poor water quality, nitrate and copper-based medications, so large, frequent water changes are essential. Handle with extreme care around the spine.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eFreshwater rays are livebearers, giving birth to small numbers of well-developed pups after a gestation of several months. Breeding is achievable only in very large, expertly managed systems, and a compatible pair like this is a starting point for the committed specialist.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003ePotamotrygon sp.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eMantilla Freshwater Stingray (pair)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eSouth America (river systems)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003eAround 35–45 cm disc width\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e10–15 years or more\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful but venomous barb; not for handling\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\u003e1000 litres or more\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eCarnivore (meaty bottom foods)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e26–29 °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 to moderately 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\u003eAdvanced keepers with very large, pristine systems\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 kept with plants (needs open sand bed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eLarge, calm, mid-to-upper water fish that ignore the bottom, such as severums, larger peaceful cichlids, silver dollars and big characins, in a suitably enormous tank.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eSmall fish, fin-nippers, aggressive cichlids, plecos that may rasp the ray's skin, and anything that competes for food on the bottom.
