Tank Size

While Corydoras can adapt to various tank sizes, a minimum of 20 gallons is recommended for a small group. Although small, these fish are social and need ample space to swim and interact freely.

Corydoras thrive in clean, well-oxygenated water. Aim for a pH level between 6.0 and 7.5, and conduct regular water changes—ideally 25% to 30% every week. Keeping water quality high is vital for their health and happiness.

Substrate and Decor

As foraging fish, it’s essential to provide them with a soft substrate, such as sand or fine gravel, to avoid injuring their sensitive barbels. Complementing this substrate with plenty of plants and decorations will enhance the visual appeal of your tank while offering hiding spots and shelter.

Diet and Feeding

Corydoras are omnivores and require a varied diet to stay healthy. Offer quality sinking pellets, and supplement their meals with frozen or live foods like brine shrimp and bloodworms. Incorporating vegetable matter is also beneficial. Feeding them two to three times daily ensures they receive balanced nutrition.
