Corydoras Habitat and Tank Setup
Appropriate Corydoras Tank Size and Type
A minimum 20-gallon tank is recommended for a small group of Corydoras. They are active and social fish, so they need space to move around and interact with their shoal. A larger tank is even better, especially if you plan to keep other fish with them.
Corydoras Water Temperature and Quality
The ideal water temperature for Corydoras is between 72-78°F (22-26°C). You’ll need to maintain stable water conditions, with a pH range of 6.0-7.8 and a hardness between 2-25 dGH. Regular water testing and partial water changes are essential to keep your Corydoras healthy and happy.
Filtration and Aeration Requirements
A good-quality filter is essential for maintaining water quality in your Corydoras tank. A gentle flow is best, as these fish come from slow-moving rivers and streams. Make sure your filter provides mechanical, chemical, and biological filtration to support the health of your fish. An air pump and air stone can be used to provide additional aeration if needed.
Corydoras do not have specific lighting requirements, but a standard aquarium light on a timer set to mimic a natural day-night cycle (10-12 hours of light) is ideal. This will help promote a healthy environment for your fish and the development of beneficial algae and plants.
Plants for Corydoras
Live plants provide numerous benefits for your Corydoras, including oxygen production, hiding spots, and natural filtration. Choose easy-to-grow plants like Java Fern, Anubias, or Amazon Sword that can tolerate a range of water conditions.
Substrate, Hideouts and Decorations
For the substrate, choose a soft, sandy material to protect the sensitive barbels of your Corydoras. Provide hiding spots such as caves, driftwood, and PVC pipes to give your fish a sense of security. Natural decorations like rocks and roots can also be used to create a more natural environment.
Aquarium Cleaning and Maintenance
Regular maintenance is essential for the health and well-being of your Corydoras. Perform weekly water tests and partial water changes (20-30% of the tank volume) to maintain ideal water conditions. Clean the filter media and vacuum the substrate as needed to remove debris and maintain water quality.
Corydoras Food and Diet
What Do Corydoras Eat?
Corydoras are omnivores and require a balanced diet of both plant-based and animal-based foods. Provide them with a mix of sinking pellets, flakes, and live or frozen foods like bloodworms, brine shrimp, and daphnia. Additionally, they will scavenge for leftover food and algae, helping to keep your tank clean.
Feeding Frequency and Schedule
Feed your Corydoras once or twice daily, providing only as much food as they can consume within a few minutes. Overfeeding can lead to poor water quality and health issues, so be mindful not to overdo it.
Occasional treats like blanched vegetables (e.g., spinach, zucchini, cucumber) or live foods can provide variety and enrichment for your Corydoras. Keep treats to a minimum and ensure they are suitable for your fish before offering them.

Common Health Issues
Corydoras, like all fish, can experience various health issues. Some common problems include fin rot, ich, and bacterial infections. To prevent these ailments, be sure to maintain a clean tank, provide a balanced diet, and monitor water parameters regularly.
