Venezuelan Corydoras

Corydoras venezuelanus

📍 South America

Ask Finn

Venezuelan corydoras is similar to the bronze corydoras but displays more orange-red colouration on the pectoral and dorsal fins, especially in males. It is hardy, adaptable, and makes an excellent beginner corydoras.

Care Guide

Diet

Venezuelan corydoras are omnivores that readily accept sinking pellets and wafers as staple foods. Supplement 2-3 times weekly with frozen bloodworms, brine shrimp, or daphnia to promote natural foraging behavior and maintain optimal nutrition. Feed small amounts once daily, removing uneaten food after 2-3 hours to maintain water quality.

Behavior

These peaceful bottom-dwellers are highly social and must be kept in groups of at least 6 individuals to exhibit natural schooling behavior and reduce stress. They spend most of their time sifting through substrate searching for food, aerating the substrate in the process. Males display vibrant orange-red coloration on their fins, especially during breeding season, making them more visually striking than females.

Breeding

Breeding Venezuelan corydoras in captivity is moderately difficult and requires cooler water temperatures (20-22°C) to trigger spawning, along with frequent water changes and abundant live food. Females will lay eggs on plants or tank surfaces after the male fertilizes them; remove eggs or parents to a separate breeding tank to prevent predation. Fry are small and require infusoria or liquid fry food for the first week before accepting microworms or newly hatched brine shrimp.

Common Diseases

Ich (Ichthyophthirius multifiliis)

Symptoms

White spots on body and fins, rapid breathing, lethargy, rubbing against objects

Treatment

Raise water temperature to 28-30°C gradually, perform daily 25% water changes, use aquarium salt (1 teaspoon per 5 gallons) or commercial ich treatment; treat for 10-14 days

Fin Rot

Symptoms

Frayed or deteriorating fin edges, discoloration at fin bases, progressive fin loss

Treatment

Improve water quality with frequent water changes, remove sharp decorations, treat with antibacterial medication or salt baths; ensure adequate aeration and maintain temperature at 24-26°C

Barbel Erosion

Symptoms

Shortened, blunt, or missing barbels; difficulty foraging on substrate

Treatment

Provide soft substrate (sand preferred over gravel), improve water quality and nutrition, reduce stress, use vitamin-enriched foods; condition usually irreversible but prevents further damage

Bacterial Infection

Symptoms

Open sores, red streaks on body, cloudy eyes, lethargy, loss of appetite

Treatment

Perform 50% water change immediately, treat with broad-spectrum antibiotic medication, maintain optimal water parameters, isolate severely affected individuals in quarantine tank
