Care Guide for Corydoras Leopardus

Corydoras leopardus is a wonderful choice for both novice and experienced aquarists. They are known for their hardy nature and peaceful temperament, making them excellent community tank residents. Here’s a comprehensive care guide to ensure their well-being in your aquarium:

Setting Up the Perfect Aquarium for Corydoras Leopardus

Creating a suitable habitat for Corydoras leopardus, the Leopard Catfish, is vital to ensure their health and happiness in your aquarium. From tank size to filtration, substrate choices, plant selection, and heating, every detail matters. Let’s delve into the specifics of setting up the perfect tank for these charming bottom-dwellers.

Tank Size: To provide ample space for your Corydoras leopardus to thrive, choose a tank with a capacity of at least 20-30 gallons. However, considering their social nature and preference for shoaling, it’s highly recommended to keep them in groups of six or more. For a school of these catfish, consider a 40-gallon or larger tank to accommodate their need for space and social interaction.

Filtration: Efficient filtration is crucial for maintaining water quality, as Corydoras are sensitive to water conditions. A reliable filter will help remove impurities and keep the water clear. Consider brands like Fluval, known for their high-quality canister filters, or Eheim for their efficient external filters. Additionally, a sponge filter can be a valuable addition, as it provides gentle, biological filtration while creating minimal water flow, which Corydoras appreciate.

Substrate: Choosing the right substrate is essential to mimic their natural habitat and protect their sensitive barbels. Opt for soft, sandy substrates like CaribSea Eco-Complete or Seachem Flourite Sand. These substrates are ideal because they won’t harm your catfish while they search for food in the substrate. A layer of 1-2 inches is sufficient to allow for natural behavior without creating maintenance challenges.

Plants: Live or artificial plants can enhance your aquarium’s aesthetics and provide hiding spots for your Corydoras. For live plants, consider species like Java Fern, Anubias, or Cryptocoryne, which are hardy and compatible with the water parameters favored by Corydoras leopardus. Alternatively, silk plants from reputable brands such as Marina or Penn Plax can provide a lifelike appearance without the need for maintenance associated with live plants.

Heating: Maintaining the right temperature is essential for the comfort of your Corydoras. A reliable heater is crucial, especially if you live in an area with fluctuating room temperatures. High-quality heaters from brands like Eheim, Aqueon, or Fluval are known for their accuracy and reliability. Aim for a temperature range of 72-78°F (22-26°C) to replicate their natural South American habitat.

Remember that Corydoras leopardus thrive in a well-maintained and carefully designed aquarium. Providing them with a spacious tank, efficient filtration, suitable substrate, appropriate plant choices, and consistent heating will create an environment where they can exhibit their natural behaviors, ensuring their health and happiness in your care. By paying attention to these details, you can enjoy the beauty and charm of these captivating catfish for years to come.

Water Parameters

  • Temperature: Keep the water temperature in the range of 72-78°F (22-26°C) to replicate their South American habitat.
  • pH Level: Aim for a slightly acidic to neutral pH range of 6.5-7.5.
  • Water Hardness: Soft to moderately hard water with a dGH of 2-12 is suitable.


  • Corydoras leopardus are bottom feeders with a voracious appetite for various types of food. Their diet should include high-quality sinking pellets, flakes, and live or frozen foods like bloodworms, brine shrimp, and daphnia.
  • Ensure regular feeding but in small portions to prevent overfeeding, as these catfish can be prone to obesity.

Tank Mates

These catfish are known for their peaceful nature, making them excellent companions for other non-aggressive fish. Ideal tankmates include tetras, gouramis, rasboras, and other small Cory catfish community fish.


  • Corydoras leopardus are schooling fish, which means they feel more comfortable and secure when kept in a group.
  • Their peaceful disposition makes them a joy to watch as they forage along the aquarium bottom and interact with each other.


  • Regular water changes of 20-25% every two weeks are crucial to maintain pristine water quality.
  • Keep an eye on their behavior and appearance; any signs of distress or illness should prompt immediate attention.

Health Considerations

  • Corydoras leopardus are generally hardy, but like all fish, they can be susceptible to diseases if their environment is not well-maintained.
  • Common fish diseases like Ich (white spot disease) can affect them, so always quarantine new additions and monitor their health closely.


In summary, Corydoras leopardus, the Leopard Catfish or Spotted Cory, is a wonderful addition to any freshwater tropical aquarium. With their eye-catching appearance, peaceful temperament, and efficient role as bottom feeders and algae eaters, they have rightfully earned their place as one of the most popular aquarium fish among enthusiasts. By providing them with a suitable environment, a balanced diet, and the companionship of their own kind, you can enjoy the beauty and charm of Corydoras leopardus for years to come. So, go ahead and add a school of these delightful catfish to your aquarium; you won’t be disappointed.
