About the Teacup Ray

The Teacup Ray, scientifically known as Potamotrygon orbignyi, is one of the smaller freshwater stingray species, making it a popular choice for hobbyists with limited space. Native to the Amazon, Orinoco, and Paraná river basins, it is named for its relatively small adult size – often compared to a teacup. Despite its smaller stature, it possesses the same charm and beauty as its larger relatives, with a distinctive reticulated pattern.

Appearance

Teacup Rays have a round to oval disc with a base color ranging from light brown to olive-gray. The disc is covered with a beautiful reticulated pattern of dark lines and spots, often forming a web-like design. Adults typically reach only 10-12 inches in disc diameter, making them one of the smallest stingrays in the hobby.

Tank Requirements

A minimum tank size of 125 gallons is recommended for a single adult Teacup Ray. Soft, sandy substrate is essential. Water parameters: temperature 78-86°F, pH 6.0-7.5.

Diet

Teacup Rays are carnivores: earthworms, blackworms, shrimp, sinking carnivore pellets, and chopped seafood. They may need smaller food items due to their smaller mouth size.
