General Description
The Northern Longnose Cory (Corydoras Septentrionalis) belongs to the Callichthyidae family. It is characterized by a noticeable barred caudal fin and a rounded body shape for females, especially when full of eggs. Typically reaching sizes of up to 6.0cm, these catfish are found in the Rio Orinoco in Venezuela and possibly Colombia.
Aquarium Setup
For an optimal aquarium setup, it is recommended to house the Northern Longnose Cory in a tank with a minimum size of 71 liters. The tank should have fine sand substrate, smooth rocks, chunks of bogwood for shelter, and areas of thick planting. Avoid undergravel filtration and ensure the substrate is clean to prevent barbel damage. Water conditions should ideally maintain a hardness of 2-15 dH, a pH of 6.0-7.5, and a temperature ranging from 22-27°C.
Behaviour
Known for their peaceful nature, Northern Longnose Corys are suitable for community tanks, preferring tankmates such as small characins, cyprinids, anabantoids, dwarf cichlids, and other peaceful catfish. It's essential to keep them in groups of at least 6 individuals to enhance their confidence and activity levels, as they thrive in the presence of conspecifics.
Feeding and Diet
These corydoras readily accept sinking dried foods, small live options, and frozen varieties like bloodworms, brine shrimp, and chopped earthworms. A varied diet is crucial to their well-being, ensuring they remain in optimal condition.
Reproduction & Dimorphism
To breed Northern Longnose Corys, set up a breeding tank with appropriate substrate and filtration. Maintain water conditions at 75-80°F and a pH of 7, with a higher ratio of males to females. Eggs are usually laid on tank glass, and spawning behavior involves males actively pursuing females in a distinctive 't-position.' Females are rounder and broader-bodied than males, especially when full of eggs. Fry care involves providing appropriate first foods and meticulous tank maintenance.
Habitat and Distribution
In their natural habitat, Northern Longnose Corys inhabit main river channels and tributaries, particularly in the Rio Orinoco in Venezuela and possibly extending into Colombia.
