Food and Feeding

False Blochi Catfish thrive on a varied diet with plenty of vegetable matter. Offer sinking algae wafers, pellets, and occasional treats of bloodworms to ensure they get their fair share of food. They also enjoy blanched vegetables like zucchini or spinach, which provide additional nutrients. Feed them during the evening hours when they are most active, as this aligns with their nocturnal habits.

Origin

False Blochi Catfish (Corydoras delphax) are native to the rivers and tributaries of Colombia, South America. These habitats are characterized by soft, slightly acidic to neutral water with sandy substrates and moderate vegetation. They are often found in slow-moving waters, which mimic their preferred aquarium conditions.

Sexing

Sexing Corydoras delphax becomes possible once they reach maturity. Females tend to be larger and have a more rounded, plump body shape, particularly noticeable when viewed from above. Males are generally slimmer and slightly smaller in size.

Breeding

Breeding False Blochi Catfish is relatively straightforward with the right conditions. Begin by lowering the water level and dropping the water temperature by a few degrees to simulate a seasonal change, which can trigger spawning. The female scatters eggs on the tank glass, plants, or substrate. After spawning, remove the adults to prevent them from eating the eggs. The eggs hatch in 3-5 days, and the fry can be fed on newly hatched brine shrimp or powdered fry food.

Lifespan

The False Blochi Catfish has an average lifespan of 3-5 years when provided with proper care, including high water quality, a balanced diet, and a stress-free environment.

Compatibility

Corydoras delphax are peaceful fish that thrive in community tanks with other non-aggressive species. Ideal tank mates include small tetras, rasboras, guppies, and other peaceful bottom dwellers like Kuhli loaches. Always keep them in groups of at least 5-6 individuals to fulfill their social needs and encourage natural behavior.

Short Description

False Blochi Catfish are a shy and peaceful species that prefer the company of their own kind. They are excellent additions to community aquariums, particularly for hobbyists looking for active bottom dwellers. Ensure their tank has open swimming spaces, sandy or fine gravel substrates, and hiding spots such as caves or driftwood. Regular water changes and stable water parameters are essential for their well-being.
