Potamotrygon Leopoldi
Common Names: Polka-Dot River Stingray, Spotted River Ray, White-Blotched River Stingray.
Distribution: Xingu and Fresco Rivers, Xingu River Basin, Brazil
Maximum Size (Disc Width): appx. 30"+, females get larger.
Juvenile Tank Footprint: 72"x18"
Adult Tank Footprint: 96"x48"
Feeding Habits: P. Leopoldi tend to finicky eaters at first, but once acclimated they have good feeding habits. Leopoldi usually accept specialty live foods upon arrival, and wean to prepared foods easily.
Info: Potamotrygon Leopoldi is one of the most sought after stingrays in the hobby. Since it's recent ban from export from Brazil, the price of Leopoldi have became increasingly high, as they are near impossible to acquire. Once acclimated, they are a very hardy and prolific ray.
Potamotrygon Henlei
Common Names: Polka-Dot River Stingray, Spotted River Ray, Orange-Blotched River Stingray, Big-Tooth River Stingray.
Distribution: Tocantins & Araguaia rivers, Tocantins River Basin, Brazil
Maximum Size (Disc Width): appx. 24"+, females get larger.
Juvenile Tank Footprint: 72"x18"
Adult Tank Footprint: 96"x48"

Potamotrygon sp. "Itaituba" - P14
Common Names: Polka-Dot River Stingray, Spotted River Ray, Galaxy River Ray, Black 'Estrella' Ray.
Distribution: Rio Tapajos, Xingu River Basin, Itaituba, Brazil
Maximum Size (Disc Width): appx. 18"+
Juvenile Tank Footprint: 72"x18"
Adult Tank Footprint: 96"x36"
Feeding Habits: P14 tend to finicky eaters at first, but once acclimated they have good feeding habits. P14 usually accept specialty live foods upon arrival, and wean to prepared foods easily.
Info: Potamotrygon sp. "Itaituba" is believed by many to be a seperate species than Leopoldi. However, others believe it is a variant of P13 Leopoldi, because of the region it is collected from. It is distinguished from normal Leopoldi by it's differentiated pattern and extra spotting around the disc margin, smaller maximum size, and a mottled underside.
P14 Note: P14 was originally designated for the Leopoldi - Eclipse variation by Dr. Ross. However, after some time in the pet trade P14 was somehow re-designated to the 'Black Estrella' or 'Black Galaxy' ray that looks similar to Leopoldi. This has created some confusion, and although P14 was first designated for Eclipse rays, it is better suited at this time for Itaituba rays
