Motoro Stingray

Species Summary


The Motoro Stingray, also known as the Ocellate River Stingray, is native to South America. The first time I saw them was in a trip to the Amazon Basin. They inhabit freshwater rivers and streams, particularly in Brazil, Argentina, and Paraguay.


With proper care, Motoro Stingrays can live up to 15 years in captivity. I’ve had mine for about 4 years now, and it’s still thriving.


A distinctive feature of Motoro Stingrays is the beautiful pattern of white spots on their brownish-green dorsal surface. These spots give them their “ocellate” name. Their eyes are on the top of their head, while their mouth is on the bottom.


When they are fully grown, Motoro Stingrays can reach up to 20 inches in diameter. My Motoro is currently about 12 inches wide, so I know it still has some growing to do.

Growth Rate

  • Motoro Stingray fry: 1-2 inches
  • Juvenile Stingray: 3-10 inches
  • Adult Stingray: 20 inches

Motoro Stingrays grow slowly, reaching their full size after 2 to 3 years. My Motoro was about 3 inches when I got it, and it has steadily grown over the years.

Behavior & Temperament

Motoro Stingrays are generally docile, peaceful, and curious creatures. When I first introduced mine to the tank, it quickly explored the space and then settled in quite comfortably.

Male Vs Female

To distinguish between a male and female Motoro Stingray, look at their tails. Males usually have a thicker tail base with a groove for the claspers, while females have a thinner tail without claspers. Due to their size and territorial nature, it’s best to keep only one Motoro Stingray per tank, regardless of their gender.

Tank Setup

Tank Size

I always recommend getting the largest tank possible for your Motoro Stingray. A minimum of 150 gallons is required, but I personally opted for a 200-gallon tank to provide ample space for my stingray to swim.


Motoro Stingrays require a moderate level of lighting. I successfully used LED lights to mimic their natural environment, providing them with a day-night cycle, ensuring not to make the tank too bright.

Filtration & Aeration

Investing in a good filtration system is crucial. For my stingray, I installed a canister filter that provides biological, mechanical, and chemical filtration. Proper aeration using an air pump is also essential to keep the stingray healthy.


It’s important to maintain an ideal water temperature of 76-82°F. To accomplish this, I use a submersible, adjustable aquarium heater and monitor the temperature with a reliable thermometer.


A soft, fine sand substrate is best for Motoro Stingrays. In my tank, I used a fine-grain sand, which helps protect their sensitive undersides.


I added some smooth rocks and driftwood to mimic their natural habitat, however, I made sure to leave plenty of open swimming space for my stingray.


I used live aquatic plants both for aesthetics and to enhance the water quality. My personal favorites are Amazon Swords and Water Wisteria as they require minimal care and are not easily uprooted.

Water Quality

Water Temperature

When I set up my stingray tank, I ensure the water temperature is suitable for a Motoro stingray. They prefer a temperature between 78°F and 82°F (25°C to 28°C). I use a high-quality heater and a precise thermometer to maintain the right temperature.

Water pH

Motoro stingrays thrive in water with a pH level between 6.0 and 7.5. I regularly monitor the pH level with a reliable test kit. Adjusting the pH is essential for their survival, so I use appropriate products, like pH buffers, to keep it in the ideal range.

Water Hardness

As for water hardness, I keep my Motoro stingray tank at a range between 5 and 10 dKH. Soft water is crucial for their wellbeing, as hard water may stress them. I use a water conditioner and test the hardness frequently to maintain these optimal levels.

Water Changes

Regular water changes are critical for preventing the buildup of toxins. In my experience, I’ve found that a weekly water change of 25% to 30% keeps the water clean and healthy. I also use a high-quality filter to remove impurities and ensure proper flow.

Tank Maintenance

When I first started keeping a Motoro Stingray in my aquarium, I learned that consistent tank maintenance is crucial. Staying committed to a strict cleaning schedule helps ensure a healthy environment for these unique creatures.

One important aspect I discovered was the need to change the water frequently. I make sure that every week, at least 25% of the water is replaced with fresh, dechlorinated water. This prevents the buildup of harmful waste and chemicals.

Another crucial task is cleaning and checking the filter. I always keep an eye on the filter’s functionality and debris buildup. Every month, I take it apart, remove any accumulated waste, and double-check that it’s still working optimally.

Controlling algae growth is essential for maintaining a pristine environment. By adjusting lighting conditions and removing any visible algae manually, I can ensure that my Motoro Stingray’s tank remains comfortably clean for them.

Additionally, using a gravel vacuum allows me to clean feces and other debris from the tank’s substrate. Confirming that the tank remains as clean as possible all the time has helped my Motoro Stingray to thrive.

In conclusion, tank maintenance is a critical aspect of Motoro Stingray care to ensure their happiness and health. By sticking to these maintenance routines, I’ve enjoyed watching my Motoro Stingray flourish and grow.

Tank Mates

Compatible Fish Species

In my experience, the best tank mates for a Motoro stingray are peaceful, non-aggressive fish that won’t become ray food or disturb the stingray’s peaceful nature. Some of these fish are:

  • Corydoras Catfish: They’re small, bottom-dwelling fish that are generally peaceful and coexist well with stingrays.
  • Plecos: Plecos, like the common or bristlenose species, are more than capable of holding their own against a stingray and can clean up any leftover food.
  • Large Cichlids: Species like the severum or blood parrots can work well as tank mates, as they’re generally non-aggressive towards stingrays.

Just remember that every stingray has its own personality, so always monitor new fish for compatibility.

Incompatible Fish Species

Sadly, I’ve discovered some fish just don’t mix with Motoro stingrays due to aggression or predatory instincts. Here are some fish I’d avoid:

  • Small fish: Tiny species like neon tetras or guppies are easy prey for stingrays and should be kept separately.
  • Predatory fish: Fish like red-tailed catfish, snakeheads, and arowanas can pose a threat to rays and even try to eat them.
  • Territorial fish: Aggressive species like some cichlids or certain catfish are known to cause harm to rays, nip at their fins, or disrupt their living environment.

Providing a calm and peaceful environment for your Motoro stingray will ensure their health and happiness in the long run.


What To Feed
