The term 'Teacup Stingray' is a highly deceptive trade name used for juvenile freshwater stingrays (often P. laticeps, P. motoro, or P. reticulata). They are not a miniature species. They are highly intelligent, predatory bottom-dwellers that require pristine water, massive aquariums, and fine sand to prevent lethal infections on their soft underbellies.

Adult (True Size)
The fully grown adult. Despite the 'Teacup' label, they reach massive proportions. They require custom footprints (minimum 180x60cm, wider is strongly preferred) and incredibly robust filtration to handle their extreme bioload.
Differs in 1 trait from base species
Also known as: Monster Ray, Adult Teacup
Juvenile (Grow-out) / 'Teacup'
The 'Teacup' sized babies sold in stores. They will outgrow standard aquariums rapidly. Even as juveniles, they require strict water quality, heavy filtration, and soft sand substrates.
Differs in 3 traits from base species
Also known as: Baby Ray, Teacup
Teacup Stingray (Common Freshwater Ray) Care Guide Summary
The Teacup Stingray (Common Freshwater Ray), scientifically known as Potamotrygon laticeps, belongs to the Oddballs family group. Adults reach a maximum size of approximately 60 cm and have a depressed body shape with a fast growth rate. Classified as semi-aggressive, this species primarily occupies the bottom zone of the aquarium and produces a extreme level of biological waste.
To thrive, the Teacup Stingray (Common Freshwater Ray) requires a freshwater only aquarium with a minimum volume of 750 litres and a tank length of at least 180 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6–7.5 and a general hardness of 1–12 dGH. A moderate water flow is preferred.
The Teacup Stingray (Common Freshwater Ray) is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Adult (True Size) and Juvenile (Grow-out) / 'Teacup'. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Teacup Stingray (Common Freshwater Ray) Habitat Setup
When setting up an aquarium for the Teacup Stingray (Common Freshwater Ray), a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels. Keepers should note that expect substrate disturbance, so lightweight décor should be secured.
Teacup Stingray (Common Freshwater Ray) Compatibility Notes
Classified as semi-aggressive, the Teacup Stingray (Common Freshwater Ray) is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, ornamental shrimp are not safe companions, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.
Teacup Stingray (Common Freshwater Ray) Feeding & Diet Considerations
The Teacup Stingray (Common Freshwater Ray) is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided, will hunt and eat ornamental shrimp, making it unsuitable for shrimp-focused setups, and will eat fry, so breeding efforts in the same tank are unlikely to succeed.

Fish Similar to Teacup Stingray (Common Freshwater Ray)
Motoro Stingray
Potamotrygon motoro
A spectacular but highly demanding freshwater stingray native to South America, instantly recognizable by its orange-spot 'peacock' pattern. They are massive, heavy-polluting predators that require huge aquariums with pristine water quality. A soft sand substrate is absolutely mandatory to prevent severe bacterial infections on their delicate underbellies. Note: They possess a venomous tail stinger.
Antennae Stingray
Plesiotrygon iwamae
The Antennae Stingray is a delicate, rare freshwater ray native to the Amazon basin. It is distinctive for its extremely long, whip-like tail that can be more than twice its disc width. They require a massive aquarium with an enormous footprint, pristine water quality, and a soft, fine sand substrate to bury themselves. As large piscivores, they will consume any tank mate small enough to fit in their mouths.
Common Pleco (Amazon Sailfin)
Pterygoplichthys pardalis
One of the most widely sold (and misunderstood) fish in the aquarium trade. Often purchased as small 'algae eaters', Common Plecos grow into massive, heavy-waste-producing giants. They require driftwood for digestion and large aquariums. As they age, they may become territorial and lazy, sometimes latching onto flat-bodied fish (like Discus) to eat their slime coat.
Silver Tiger Perch (American Tigerfish)
Datnioides polota
A large, predatory, and fascinating species widely known in the hobby as the 'American Tigerfish' (AT) or Silver Datnoid. Note: Scientific consensus now recognizes Datnioides polota as the valid name, with D. quadrifasciatus often used as a synonym. Naturally found in brackish estuaries and river mouths, they adapt to freshwater but thrive in hard, alkaline, light-brackish conditions. They are aggressive predators and best kept singly or in very large groups.
Twig Catfish (Farlowella)
Farlowella acus
The Twig Catfish is an extremely elongated, master-of-camouflage suckermouth catfish from South America. True to its name, it mimics a dead twig perfectly, spending most of its time motionless on branches or plant leaves. It is a specialized aufwuchs and algae grazer that requires a mature tank, high oxygenation, and plenty of driftwood. They are completely peaceful but highly sensitive to fluctuating water parameters.
Common Whiptail Catfish
Rineloricaria eigenmanni
A highly distinctive, slender, and peaceful bottom-dwelling catfish from South America. Known for its extremely elongated tail and excellent camouflaging abilities. They are non-aggressive grazers that feed on biofilm, aufwuchs, and sinking foods. Their rigid, twig-like bodies mean they need broad, smooth resting places.
