Habits and Lifestyle
Motoro Stingrays are primarily bottom dwellers, spending most of their time on the substrate where they search for food. They are generally peaceful but require ample space to move and hide. These stingrays are known for their ability to sense electrical fields in the water, which helps them locate prey.
Care Guide
Tank Setup: A tank of at least 200 gallons is recommended, with a fine, sandy substrate to prevent damage to their undersides. Provide plenty of hiding spots such as rocks, driftwood, and large plants.
Water Parameters: Maintain a pH of 6.5-7.5 and a temperature of 75-82°F. Efficient filtration and regular water changes are crucial for maintaining high water quality.
Diet: Feed a diet rich in protein, including live or frozen foods like shrimp, earthworms, and small fish. They may also accept high-quality carnivore pellets.
Physical Characteristics
Motoro Stingrays can grow up to 24 inches in diameter. They have a round, flat body with a pattern of bright spots on a dark background, a long tail equipped with venomous spines, and a mouth located on the underside.
Diet and Nutrition
These stingrays are carnivorous and thrive on a diet of live or frozen foods such as shrimp, earthworms, and small fish. Offering a variety of protein-rich foods helps ensure they receive balanced nutrition.
Breeding and Business
Breeding Motoro Stingrays in captivity can be challenging but is possible with the right conditions. They are livebearers, meaning they give birth to live young rather than laying eggs.
Breeding Techniques: To breed Motoro Stingrays, set up a large breeding tank with plenty of hiding spots. The water should be clean and stable with a temperature around 80°F. After a gestation period of several months, the female will give birth to live young.

Maintaining high water quality and a proper diet can help prevent these issues. Regular health checks and quarantine of new fish can also mitigate disease risks.
Common Diseases:
- Ich: Symptoms include white spots on the body and fins. Treat with elevated water temperatures and ich-specific medication.
- Bacterial Infections: Look for redness, ulcers, or fin rot. Antibiotic treatments in a quarantine tank are usually effective.
- Parasites: Symptoms include scratching against objects and rapid breathing. Anti-parasitic medications can help.
Commercial Medicines: Some commonly used medications for treating diseases in Motoro Stingrays include:
- Ich Treatment: Malachite Green, Formalin
- Bacterial Infections: Maracyn, Kanamycin
- Parasites: Praziquantel, Metronidazole
