Freshwater Black Diamond Stingray (X)

The Freshwater Black Diamond Stingray is one of the most striking and highly sought-after freshwater rays in the aquarium hobby. Known for its deep black body adorned with vivid white or cream-colored spots, this ray is the result of selective breeding that enhances contrast and pattern density. The “X” variant typically exhibits even more defined markings and a cleaner, more symmetrical spot distribution, making it a true showpiece for any large display tank.

Native to the river systems of South America, the Black Diamond Stingray is a bottom-dwelling species that spends much of its time gliding over sandy substrates in search of food. Its beauty is matched by its grace, with smooth, fluid movements that make it a captivating presence in the aquarium.

In captivity, the Black Diamond Stingray requires a minimum tank size of 300 gallons, though larger is always better for adult specimens. The aquarium should feature a soft sand substrate to prevent irritation to its delicate underside. Smooth rocks and driftwood can be added for aesthetics, but most of the space should remain open for swimming. Water quality is critical—stable temperatures between 26–29°C (79–84°F), soft to moderately hard water, and robust filtration are essential for long-term health.

Feeding this ray is relatively straightforward. It will accept a variety of meaty foods, including shrimp, earthworms, small fish, and frozen or live bloodworms. Due to its size and feeding habits, it should only be housed with other large, peaceful fish that will not nip at its disc or compete aggressively for food.

Because of their rarity, specialized care requirements, and stunning appearance, Black Diamond Stingrays are best suited to experienced aquarists who can meet their needs. With proper care, they can live for many years, serving as the centerpiece of a large, well-maintained freshwater aquarium.
