Pure Motoro Freshwater Stingray Care Guide

Introduction

The Pure Motoro Freshwater Stingray (*Potamotrygon motoro*) is an impressive and majestic species of stingray native to the rivers of South America, particularly in the Amazon and Orinoco basins. Known for its distinctive pattern and large size, this species is a sought-after addition to specialized aquariums. With proper care, the Motoro stingray can thrive in both home aquariums and larger public displays.

Natural Habitat

The Pure Motoro Stingray is found in the slow-moving, murky waters of the Amazon River and its tributaries. These rays typically live in sandy or muddy riverbeds where they can easily camouflage and forage for small invertebrates, mollusks, and detritus. They are well-adapted to their environment, using their disc-shaped bodies to bury themselves in the substrate.

Aquarium Setup

A tank of at least 180 gallons (around 680 litres) is recommended for a single Pure Motoro Freshwater Stingray, with larger tanks required for multiple rays. The aquarium should have a soft, sandy substrate to allow the ray to dig and bury itself comfortably. The tank should also have plenty of hiding spots created with rocks or driftwood, and it is essential to provide strong filtration to maintain high water quality.

Water Parameters

The ideal water temperature for Pure Motoro Stingrays ranges from 75°F to 82°F (24°C to 28°C), with a pH level between 6.5 and 7.5. These rays thrive in slightly acidic to neutral water conditions. Regular water changes of about 25-30% per week are necessary to maintain water quality, as stingrays are sensitive to poor water conditions.

Diet and Feeding

Pure Motoro Freshwater Stingrays are carnivorous and require a diet rich in protein. They can be fed high-quality sinking pellets, live or frozen foods such as bloodworms, brine shrimp, earthworms, and small fish. It is also beneficial to offer mollusks or shellfish, which help keep their teeth worn down. A varied diet supports their health and ensures they receive all the essential nutrients they need.

Behaviour and Social Structure

This species is typically peaceful but can be shy and reclusive, especially when first introduced to a new environment. Motoro stingrays prefer to spend their time on the bottom of the aquarium, where they may bury themselves in the substrate. While they can be kept with other peaceful bottom dwellers, care should be taken to avoid overly aggressive tank mates that could stress them.

Compatibility with Other Species

Pure Motoro Freshwater Stingrays are best kept with large, non-aggressive fish that share similar water requirements. Suitable tank mates include large catfish, peaceful cichlids, and other rays. It is important to avoid smaller fish that could be seen as food or species that may harass or stress the ray. Stingrays also require plenty of space to swim freely, so overcrowding should be avoided.

Breeding

Breeding Pure Motoro Freshwater Stingrays in captivity is challenging and rare. They are viviparous, meaning they give birth to live young rather than laying eggs. A successful breeding environment requires stable water conditions, proper nutrition, and a large enough tank to accommodate the gestation period. Females typically give birth to a small number of pups, which are fully formed and capable of swimming immediately after birth.

Health Considerations

Pure Motoro Freshwater Stingrays are generally hardy but can be susceptible to certain diseases, including skin infections, parasites, and poor water quality-related issues like ich or fin rot. Regular tank maintenance, water changes, and monitoring for early signs of illness are essential to ensure their well-being. It is also important to provide a varied and balanced diet to support their immune system.

Conclusion

The Pure Motoro Freshwater Stingray is a beautiful and fascinating species that can make an excellent addition to a properly set up aquarium. With their unique appearance and peaceful temperament, they are a rewarding species for dedicated aquarists with the space and resources to care for them. With proper care, a well-maintained environment, and attention to their needs, they can thrive and provide years of enjoyment.
