Ideal Tank Setup

A minimum tank size of 20 gallons is recommended. Use a soft, sandy substrate to protect their sensitive barbels and long snout. Add decorations such as driftwood, caves, and plants to replicate their natural habitat and provide hiding spots. Maintain water parameters with a pH of 6.5–7.5, a temperature of 22–26°C, and gentle water flow to mimic their native environment.

Compatible Tank Mates

Feeding and Nutrition

This omnivorous species enjoys a varied diet. Provide high-quality sinking pellets as a staple, and supplement it with live or frozen foods like bloodworms and brine shrimp. Blanched vegetables, such as zucchini or spinach, are also appreciated. Feed them 2–3 times daily in small portions to keep them healthy and active.

Breeding and Behaviour

Breeding Northern Longnose Cory Catfish can be achieved with the right conditions. Males are smaller and slimmer than females. To encourage spawning, mimic rainy-season conditions with regular water changes and slightly cooler water temperatures. Females lay adhesive eggs on flat surfaces, and the fry hatch within 4–6 days. Feed fry powdered or liquid fry food for proper development.
