• GH Level: Aim for a general hardness (GH) level of 4 to 10 dGH.
• KH Level: Keep the carbonate hardness (KH) within the range of 2 to 8 dKH to ensure stable water conditions.

Feeding: The Northern Longnose Corydoras is an omnivorous bottom-feeder with a varied diet. Provide the following:

• Pellets: High-quality sinking pellets designed for bottom-feeding fish.
• Live or Frozen Foods: Offer live or frozen foods such as bloodworms, brine shrimp, or daphnia to supplement their diet with protein.
• Vegetables: Include occasional offerings of blanched vegetables like zucchini or spinach to add fiber and variety to their diet.

Tank Mates: The Northern Longnose Corydoras is a peaceful and social fish that does well with a variety of tank mates. Suitable companions include other Corydoras species, small non-aggressive fish, and peaceful invertebrates. Avoid larger or aggressive fish that may intimidate or prey on the Corydoras.

Substrates and Tank Decorations: A soft, sandy substrate is ideal for the Northern Longnose Corydoras, as it allows them to forage comfortably and prevents injury to their sensitive barbels. Incorporate hiding spots such as rocks, driftwood, and plants to create a comfortable environment and encourage natural behaviors.

Suitable Plants: Live plants can enhance the tank environment for Northern Longnose Corydoras. Hardy plants like Java Fern, Anubias, and Cryptocoryne are good choices. Floating plants like Hornwort can also provide additional cover and help maintain water quality.

Sexing: Sexing Northern Longnose Corydoras can be challenging. Generally, males are slightly smaller and slimmer than females. Females may also have a more rounded abdomen, especially when carrying eggs.

Breeding: Breeding Northern Longnose Corydoras in captivity can be successful with proper conditions. They are egg-scatterers and will lay their eggs on flat surfaces or in hiding spots. Maintain stable water conditions and provide plenty of hiding places for the eggs and young fry. After hatching, the fry will need fine food such as powdered fry food or liquid fry food to grow.

Maximum Size and Longevity: Northern Longnose Corydoras typically grow to about 2.5 to 3 inches (6 to 8 cm) in length. With proper care, they can live up to 5 to 7 years in captivity.

General Information: The Northern Longnose Corydoras is a charming and peaceful catfish known for its elongated snout and attractive appearance. It thrives in well-maintained aquariums with suitable tank mates and environments. Its active bottom-feeding behavior and social nature make it a favorite among aquarium enthusiasts.

A Fun Fact: The elongated snout of the Northern Longnose Corydoras is an adaptation that helps it search for food in the substrate. This specialized feature allows it to effectively forage for small invertebrates and detritus, contributing to the overall cleanliness of the aquarium.
