Henlei Stingray (Potamotrygon henlei)
Henlei Stingray (Potamotrygon henlei)
The Black Diamond of the Amazon
The Henlei Stingray (Potamotrygon henlei) is one of the most iconic and sought-after freshwater stingrays in the world. Revered as the true “Black Diamond,” this species is prized for its deep jet-black base coloration adorned with crisp white to golden spotting, creating a dramatic, high-contrast appearance unmatched in the hobby.
Native to the Rio Tocantins system in Brazil, P. henlei is known for its bold patterning, refined disc shape, and strong presence. Each specimen is unique, with variations in spot size, density, and intensity—making high-quality individuals especially valuable to collectors and enthusiasts.
Care
Henlei stingrays require pristine water conditions, stability, and dedicated care, making them best suited for experienced aquarists.
- Temperature: 78–84°F (25–29°C)
- pH: 6.0–7.2
- Water Hardness: Soft to moderately soft
- Behavior: Peaceful, active bottom dweller
- Experience Level: Advanced
Exceptional filtration, heavy aeration, and frequent water changes are essential. Rays are sensitive to ammonia and nitrite and require stable, mature systems.
Diet
Carnivorous and highly responsive feeders.
- Fresh or frozen shrimp, worms, and fish
- High-quality stingray pellets (can be trained)
- Occasional live foods
A varied, protein-rich diet is critical for growth, coloration, and overall health.
Tank Size
- Minimum Tank Size: 180 gallons (juveniles)
- Recommended: 300+ gallons for adults
A wide footprint is far more important than height. Use fine sand substrate and avoid sharp décor. Open bottom space is essential.
Tank Mates
Compatible with large, peaceful to semi-aggressive species that occupy the upper water column.
- Suitable: Arowana, datnoids, large cichlids, peaceful catfish
- Avoid: Aggressive fin-nippers, overly boisterous fish, or species that may harass the ray
Careful selection is key to reducing stress and ensuring long-term success.
Summary
The Henlei Stingray stands as a true pinnacle species in the freshwater hobby. With its striking “Black Diamond” appearance and commanding presence, it represents both beauty and prestige. For aquarists prepared to meet its demands, Potamotrygon henlei delivers an unparalleled showpiece experience.
