🐟 Henlei Stingray (Potamotrygon henlei)
A Near-Black Disc Scattered With Bold Yellow-White Spots • A Captive-Bred Showpiece Ray • A Gentle Giant for the Large Display Tank
📋 The Henlei Stingray, also known as the Bigtooth River Stingray, Black Stingray or P12, carries a dark brown to near-black disc scattered with large yellow-white spots and a ring of smaller spots around the edge. That striking pattern makes it one of the most sought-after rays in the hobby.
It comes from South America, from the Tocantins and Araguaia river basins of Brazil, where it glides over sandy and muddy river bottoms. Wild exports from Brazil are restricted, so captive-bred Henlei like ours are a prized find. Every Henlei Stingray we ship is feeding well.
This is a true livebearer, giving birth to small, fully formed pups. It's a peaceful, curious bottom dweller that quickly learns its feeding routine and will often rise to the surface at mealtimes. It spends its days gliding over open sand, so a wide footprint and a soft, fine sand bottom matter more than tank height. Like all freshwater rays, it carries a barb on the tail, so work with care during tank maintenance. It grows up to 60cm across the disc, plus the tail, so a 1,000L tank suits it well.
