Food and Feeding

Twosaddle Corydoras are omnivorous and thrive on a varied diet. Use sinking pellets or wafers as a staple food, preferably algae-based, to ensure they can feed comfortably at the bottom levels of the tank. To keep them in top condition, supplement their diet with occasional treats of live or frozen bloodworms and brine shrimp. Feed them in the evening when they are most active, and ensure their tank mates do not outcompete them for food.

Origin

Native to the lush waterways of Peru, Corydoras weitzmani inhabit slow-moving rivers and streams with soft, slightly acidic water. Their natural environment often includes dense vegetation and sandy or fine-gravel substrates, which provide both food sources and protection.

Sexing

Sexing Twosaddle Corydoras becomes more apparent as they mature. When viewed from above, females are slightly larger and exhibit a plumper body shape compared to the slimmer males.

Breeding

Breeding Corydoras weitzmani is relatively straightforward, making them a great choice for aquarists interested in breeding fish. Regular water changes with soft, slightly cooler water can trigger spawning. The females scatter eggs around the tank, often attaching them to plants or other surfaces. To protect the eggs, consider moving them to a separate breeding tank. Once hatched, feed the fry Infusoria or finely crushed flake food, transitioning to newly hatched brine shrimp as they grow.

Lifespan

With proper care and optimal conditions, the average lifespan of Corydoras weitzmani is 3-5 years.

Tank Setup and Behavior

Twosaddle Corydoras are peaceful and social fish, thriving in groups of at least five individuals. A sandy or fine gravel substrate is essential to protect their delicate barbels, and the tank should include hiding spots such as driftwood, caves, and plants to mimic their natural habitat.

They coexist well with other gentle and similarly sized species, such as:

• Neon Tetras – Vibrant and peaceful tank mates.
• Ember Tetras – Small and serene companions.
• Harlequin Rasboras – Ideal for a harmonious community tank.
• Otocinclus Catfish – Complementary bottom dwellers.
• Bolivian Rams – Gentle dwarf cichlids that pair well with Corydoras.
