How big do panda corydoras get? This question often arises among aquarium enthusiasts and those considering adding these delightful fish to their aquatic community. Understanding the size of panda corydoras is crucial for planning a suitable tank and providing the right care. In this discussion, we will explore the typical size range of panda corydoras, shedding light on their dimensions as they mature. By the end, you’ll have a clear understanding of just how big panda corydoras get and how to accommodate their needs in your aquarium.

So, How Big Do Panda Corydoras Get?

When fully grown, panda corydoras typically reach a size of around 1.5 to 2 inches (3.8 to 5 centimeters) in length. They are considered a small species among corydoras catfish and are well-suited for small to medium-sized aquariums.

Keep in mind that the size of panda corydoras can vary slightly from one individual to another, but they generally fall within the mentioned size range. Providing them with proper care, such as a suitable tank size, water conditions, and a balanced diet, will help ensure their health and well-being in your aquarium.

Feeding and Growth

When wanting to know the answer to the question, ‘how big do panda corydoras get?’, feeding your panda corydoras properly is essential for their growth and overall health. These fish are omnivores, meaning they eat both plant matter and small protein-based foods. Here are some tips on how to feed them to promote growth:

  • High-Quality Pellets or Flakes: You can start with high-quality sinking pellet or flake food specifically formulated for bottom-dwelling fish like corydoras. Look for a product that lists fish or shrimp meal as the primary ingredient and contains essential nutrients like protein, vitamins, and minerals.
  • Variety in Diet: While pellets or flakes can be a staple of their diet, it’s important to offer variety. Supplement their diet with frozen or live foods such as bloodworms, brine shrimp, daphnia, and blackworms. These live or frozen foods are rich in protein and can help stimulate growth and provide a well-rounded diet.
  • Vegetable Matter: Panda corydoras also benefit from occasional plant matter in their diet. You can offer blanched vegetables like zucchini, cucumber, or spinach. These provide fiber and help balance their diet.
  • Feed in Moderation: Overfeeding can lead to health issues and water quality problems in your aquarium. Offer small, frequent meals rather than large quantities of food. Only provide what the fish can consume in a few minutes, and remove any uneaten food to prevent it from fouling the water.
  • Sinking Food: Corydoras are bottom-dwelling fish, so make sure the food you offer sinks to the substrate. This ensures they have easy access to their food.
  • Supplemental Feeding: You can also use specialized corydoras pellets or wafers to ensure they get the nutrition they need. These foods are designed to sink quickly and provide balanced nutrition for bottom-dwelling catfish.
  • Observation: Pay attention to the individual needs and preferences of your panda corydoras. Some fish may have specific food preferences, so monitor their behavior and adjust their diet accordingly.
  • Water Quality: Maintaining good water quality in your aquarium is crucial for the overall health and growth of your fish. Regular water changes, proper filtration, and monitoring water parameters are essential.

Remember that proper nutrition is just one aspect of promoting healthy growth in panda corydoras. Providing a suitable aquarium environment with appropriate water parameters (temperature, pH, hardness) and plenty of hiding spots and clean substrate is equally important. A well-maintained and properly stocked aquarium will contribute to the overall well-being and growth of your panda corydoras.

Aquarium Environment

Setting up the aquarium properly is essential for optimizing the health and growth of your panda corydoras. Here are some key considerations:

  • Tank Size: Panda corydoras are relatively small fish, but they are active and social, so a larger tank is better. A 20-gallon (75 liters) tank is a good starting point for a small group of panda corydoras. A larger tank allows for more swimming space and provides better water stability.
  • Substrate: Use a fine-grained substrate like sand or smooth gravel for the bottom of the tank. Corydoras are bottom-dwelling fish, and a soft substrate helps prevent injury to their delicate barbels while foraging for food.
  • Water Parameters: Maintain stable water conditions by keeping an eye on the following parameters: Keep the water temperature between 72°F to 78°F (22°C to 26°C). Aim for a pH level around 6.5 to 7.5.
  • Filtration: Provide efficient filtration to keep the water clean and well-oxygenated. Corydoras are sensitive to poor water quality, so a good filter is essential. Ensure that the filter’s outflow doesn’t create strong currents near the bottom of the tank, as corydoras prefer calmer areas.
  • Decorations and Hiding Places: Create a natural-looking environment with live or artificial plants, driftwood, and rocks. Pandas corydoras appreciate hiding spots, so consider adding caves or PVC pipes for them to retreat to when they feel stressed or during breeding.
  • Lighting: Use subdued lighting to mimic their natural habitat, as panda corydoras come from dimly lit streams and rivers. Bright lighting can stress them, so provide plenty of shaded areas.
  • Tank Mates: Choose tank mates carefully. Panda corydoras are peaceful fish, but they can be sensitive to aggressive or nippy tankmates. Ideal tank mates include other small, peaceful community fish like tetras, rasboras, and small peaceful catfish species.
  • Group Size: Corydoras are social fish, so it’s best to keep them in a group of at least six individuals or more. A larger group will make them feel more secure and reduce stress.
  • Water Changes: Perform regular water changes of around 20-30% of the tank volume every 1-2 weeks to maintain water quality. Be sure to use a water conditioner to remove chlorine and chloramines from tap water, if necessary.
  • Feeding: As mentioned in the previous section, provide a varied diet with a mix of high-quality pellets, live or frozen foods, and occasional plant matter. Ensure that the food reaches the bottom for easy access by your corydoras.

By creating a well-balanced and comfortable environment for your panda corydoras, you can help optimize their health and promote their growth. Regular observation and maintenance are also important for ensuring their well-being in your aquarium.


In conclusion, when considering the size of panda corydoras, it’s important to note that these charming fish typically reach a size of around 1.5 to 2 inches (3.8 to 5 centimeters) when fully grown. This makes them an ideal choice for smaller aquariums, given their compact stature. So, if you’ve ever wondered, “How big do panda corydoras get?” the answer is clear: they remain relatively petite in size throughout their lives. Proper care, including a well-balanced diet and a thoughtfully designed aquarium environment, will help ensure that your panda corydoras thrive and maintain their characteristic charm in your aquatic setup.
