Long-nosed Fairy Cory Care Guide - Aquarium Tips, Diet & Breeding

The Long-nosed Fairy Cory is a small, elegant armoured catfish with a noticeably elongated snout and a pale body patterned with dark markings. Its back is typically tan to silvery brown, while the sides and fins carry subtle spotting and shading that help it blend into a sandy, leaf-strewn riverbed.

Like other Corydoras, it has rows of protective bony plates rather than ordinary scales and uses pairs of barbels around its mouth to investigate the substrate. These sensitive whisker-like organs help it locate small food items among sand and detritus.

This species is peaceful, active and sociable, spending much of its time foraging across the bottom but occasionally darting to the surface to gulp air. Its ability to take atmospheric oxygen is a natural adaptation and is not a sign that the fish is necessarily unwell.

In the wild, Long-nosed Fairy Corys live in loose groups and are most engaging when kept alongside their own kind. They may rest together on the substrate, then become lively and purposeful when exploring their surroundings or searching for food.

Corydoras sychri is native to Peru in South America, where it occurs in tributaries and river environments associated with the upper Amazon basin, including the Río Marañón drainage. It is a freshwater species from warm, seasonally variable tropical waters.

A group of Long-nosed Fairy Corys should have an aquarium of at least 60 litres, with a footprint of approximately 60 by 30 cm or larger. Use fine, smooth sand or another soft substrate so their delicate barbels are not damaged while foraging. Provide open bottom areas, shaded retreats, smooth wood, rounded stones, hardy plants and some leaf litter, while leaving gentle-flowing areas for exploration. Securely cover the aquarium, as Corydoras may jump when startled, and maintain clean, well-oxygenated water without excessive current.

Males usually reach about 4.5 cm (1.8 inches), while females may grow to around 5.5 cm (2.2 inches) in total length. Exceptional females may approach 6 cm (2.4 inches).

Offer a varied omnivorous diet of sinking micro-pellets, quality catfish tablets and small granules, supplemented with frozen or live foods such as bloodworm, daphnia, blackworm and brine shrimp. They naturally sift through the substrate for small invertebrates and organic particles, but should not be expected to survive on leftover food alone. Feed enough sinking food for every fish to eat, rather than relying on algae wafers intended for herbivorous species.

Long-nosed Fairy Corys are peaceful community fish and can be kept with small, calm species such as ember tetras, small rasboras, pencilfish, peaceful livebearers, honey gouramis and other non-aggressive South American community fish. They also mix well with other similarly sized Corydoras when sufficient bottom space is available. Avoid large or boisterous fish, fin-nippers, aggressive cichlids and species that compete intensely for food, as well as any tankmate likely to swallow or harass them.

Long-nosed Fairy Corys are egg scatterers that can breed in a mature, well-conditioned aquarium. Condition a group with varied, protein-rich foods, then encourage spawning with a partial water change using slightly cooler water. The female carries a few eggs between her pelvic fins while a male fertilises them, after which she places them on aquarium glass, plants or other smooth surfaces. Remove the adults or protect the eggs from being eaten; the eggs usually hatch in around three to five days, and the tiny fry can be raised on infusoria or suitably fine first foods before moving on to newly hatched brine shrimp.

Females are generally broader-bodied and slightly larger than males, especially when viewed from above. Males are usually slimmer and a little shorter, although the difference can be subtle outside a mature group.
