Corydoras Catfish

Corydoras typically live for 5 to 10 years in a well-maintained aquarium. With the right water conditions, diet, and care, some species can live even longer. A stable tank environment and a balanced diet help them reach their full lifespan.

Corydoras are omnivores and enjoy a varied diet. They thrive on sinking pellets, high-quality flakes, and occasional live or frozen foods such as bloodworms, brine shrimp, and daphnia. They will also scavenge the tank for leftover food, so it's important not to overfeed. Feeding small amounts two to three times a day is ideal.

There are many species of Corydoras, including popular varieties like the Bronze Corydoras, Panda Corydoras, Albino Corydoras, and Sterba’s Corydoras. While their care needs are similar, each species may have slightly different preferences when it comes to water parameters especially in those corydoras wild types, so it's important to research your specific species.

Corydoras are small fish, with most species growing to around 5 cm in length. Some species, such as Corydoras aeneus (Bronze Cory), may reach up to 7 cm. Their small size makes them ideal for smaller aquariums, but they still need plenty of space to move and scavenge. The Pygmy Corydoras is a very small variety and makes for a great nano tank fish option.

Yes, Corydoras are tropical fish and require water temperatures between 22°C and 28°C. A heater is essential to maintain a stable environment. Fluctuating temperatures can stress them out and make them more susceptible to disease, so a heater ensures that the water stays within their preferred range.

A minimum tank size of 40 L is recommended for a small group of Corydoras. They thrive in soft, slightly acidic to neutral water (pH 6.0–7.5). Corydoras are bottom dwellers, so a tank with smooth sand or fine gravel substrate is ideal to protect their sensitive barbels. Adding plants, driftwood, and hiding places will provide them with a natural, comfortable environment. Ensure gentle filtration as strong currents can stress them.

Yes, Corydoras are peaceful and social fish that do well in community tanks. They are non-aggressive and can be kept with other peaceful species such as tetras, rasboras, and small livebearers. However, they should be kept in groups of at least 4 to reduce stress, as they are shoaling fish. Avoid keeping them with large or aggressive species that may intimidate or harm them.

In Corydoras, females are generally larger and rounder than males, especially when they are carrying eggs. The males tend to be slimmer and more slender. Additionally, during breeding, males may chase the females and display more intense colouring or fin movement.
