Species Summary


The Pearl Stingray (Potamotrygon sp.) originates from the freshwater rivers of South America, particularly in the Amazon Basin. I remember my first encounter with this fascinating species during a trip to Brazil.


Pearl Stingrays can live for around 15-20 years in captivity with proper care and a well-maintained environment.


This species is known for its stunning looks, featuring an exotic, pearl-like pattern on its back. I was captivated by their appearance when I first saw one in person.


Pearl Stingrays grow to be roughly 18-24 inches in diameter, making them a sizable addition to any aquarium or pond.

Growth rate

These stingrays have a moderate growth rate, reaching their full size in about 3-4 years.

Behavior & Temperament

Pearl Stingrays are generally shy and docile creatures that tend to be active during the night. In my experience, they are peaceful with other tank mates as long as they are not threatened or overcrowded.

Male vs Female

Males and females look quite similar, but males have slightly slimmer and more pointed tails than females. When I was choosing a pair for my aquarium, this distinction helped me greatly.

Tank Setup

Tank Size

When I first set up a tank for my Pearl Stingray, I ensured it was at least 125 gallons, as these rays can grow up to 2 feet. I made room for the tank, as a bigger tank gives them more space to swim.


I installed dimmable LED lights to mimic their natural habitat. Pearl Stingrays prefer subdued lighting, so I made sure not to make it too bright.

Filtration & Aeration

Pearl Stingrays produce a lot of waste, so I opted for a powerful canister filter. Additionally, I added an air pump to ensure proper oxygen exchange and water movement.


The water temperature in my tank is maintained between 76-82°F with a high-quality heater. It’s essential to have a stable temperature for their well-being.


I used sand as the substrate in my tank since Pearl Stingrays love to dig and hide. It’s also softer on their body compared to gravel.


I added driftwood and rocks, providing hiding spots for my stingray. I also ensured there were open spaces for the ray to swim freely.


To further emulate their natural habitat, I included live plants in my tank. They provide not only hiding spots but also help with water quality. Just be cautious not to overcrowd the tank with too many plants.

Water Quality

Water temperature

When I first set up my Pearl Stingray tank, I made sure that the water temperature was between 76-82°F (24-28°C). Higher temperatures increase their metabolism, while cooler temperatures help minimize stress. Investing in a good quality heater and thermometer ensures the temperature remains stable.

Water pH

The next important parameter for a Pearl Stingray tank is pH. I maintain the pH between 6.5 and 7.5. Having a pH test kit is crucial for regular check-ups, as improper pH levels can lead to diseases and skin irritations.

Water Hardness

Pearl Stingrays prefer moderately soft to slightly hard water. I keep my tank’s water hardness between 5-15 dGH. Using a GH test kit, I monitor the hardness levels and adjust accordingly by adding hard water or mixing RO water with tap water.

Water changes

Regular water changes are essential for the well-being of your Pearl Stingray. I carry out 20-30% water changes every two weeks, making sure to also vacuum the substrate. This helps in reducing toxins and maintaining ideal water parameters.

Tank Maintenance

When I first started taking care of a Pearl Stingray, maintaining the tank cleanliness was crucial for its overall health. Regular tank maintenance ensures that their living environment stays safe and clean.

In my experience, it’s essential to check the water quality frequently. I keep an eye on the ammonia, nitrite, and nitrate levels every week. This is especially important since Pearl Stingrays can be sensitive to changes in water quality.

I perform water changes at least once every two weeks, replacing about 20-25% of the tank water. This helps remove any excess waste and keep the water chemistry stable.

One thing I noticed when keeping a Pearl Stingray was the importance of adequate filtration. I made sure to invest in a high-quality and efficient filter to remove waste, and I also clean the filter media regularly.

Although Pearl Stingrays can adapt to various water conditions, I found that it’s crucial to maintain a stable water temperature of around 75-82°F (24-28°C) and a pH level between 6.0-7.5.

I also introduced some tank decorations, such as driftwood or cave-like structures, giving my stingray a sense of security and natural habitat.

As an anecdote, I made sure to keep all my electrical equipment (heaters, filters, etc.) working correctly by regularly checking them and conducting maintenance when needed. This ensured that my Pearl Stingray’s environment stayed stable and safe.

In the end, maintaining a clean and healthy tank environment is essential to a Pearl Stingray’s wellbeing. By regularly monitoring and performing maintenance tasks, I can ensure that my stingray enjoys a comfortable and happy life in its tank.

Tank Mates

Compatible Fish Species

In my experience, Pearl Stingrays can live peacefully with several other fish species. It’s essential to choose tank mates that won’t cause stress or harm to your ray. Here are some compatible fish species:

  • Catfish: I’ve found that larger catfish species like the Pictus or Redtail catfish make great tank mates due to their peaceful nature and ability to coexist with rays.
  • Cichlids: While some cichlids can be territorial, I successfully kept Geophagus and Green Terrors with my Pearl Stingray.
  • Larger Tetras: Fish like Silver Dollars and Congo Tetras seem to do well with stingrays, as they aren’t easily intimidated by their larger tank mates.

Incompatible Fish Species

Of course, not all fish can coexist with a Pearl Stingray. In my experience, there are certain species that you’ll want to avoid:

  1. Aggressive Fish: Avoid adding any fish known for their aggression, like Oscars or Jack Dempseys, to your stingray tank. They might attack or stress out your ray.
  2. Small, Delicate Fish: Smaller, delicate fish like neon tetras, guppies, and bettas may become easy prey for your ray.
  3. Bottom-Dwellers: Pearl Stingrays love to dig and explore the bottom of the tank, so it’s best not to keep other bottom-dwelling species like corydoras or loaches as tank mates, as they may compete for space and resources.

It’s crucial to remember that each fish’s temperament can vary, so always keep an eye on new tank mates and be ready to make adjustments if necessary. My Pearl Stingray surprisingly got along well with a few species I initially thought might be incompatible. So, always be open to surprises! Just ensure the well-being of your Pearl Stingray and its tank mates is the top priority.


What To Feed

When I first got my Pearl Stingray, I did extensive research on their diet. I found that they primarily eat bottom-dwelling creatures. Here’s a list of suitable foods to feed your Pearl Stingray:

  • Frozen or live food: Bloodworms, brine shrimp, mysis shrimp, and krill.
  • Fresh food: Chopped fish, mussels, and cockles.


In my experience, Pearl Stingrays should be fed at least twice a day. It’s best to feed them smaller amounts multiple times a day to mimic their natural feeding habits. I usually feed my stingray in the morning and evening, and I adjust the feeding amount based on its growth and activity level.


Feeding your Pearl Stingray a varied diet is essential to ensure they get all the nutrients they need. Here are some tips I learned along the way:

  1. Introduce a variety of food items: Offering different food sources helps increase the chances of your stingray getting a balanced diet.
  2. Monitor their intake: Make sure they eat the food you offer; uneaten food can spoil and affect the water quality.
  3. Use feeding tools: To avoid being stung, use long feeding tools or place food in their feeding area with tongs.

Remember, it’s essential to keep a close eye on your Pearl Stingray’s diet to ensure its health and well-being. Investing time and effort in maintaining an appropriate diet is crucial for their long-term care.
