Leopard Corydoras C102 Care Guide - Aquarium Setup, Diet & Breeding

Leopard Corydoras C102 is an undescribed, naturally occurring corydoras known in the aquarium hobby by its C-number rather than a formally established species name. Its compact body is marked with dark leopard-like spotting and broken patterning over a pale silver, beige or golden-brown background, giving it a distinctive appearance among small armoured catfish.

Like other members of the genus, it has a flattened underside, rows of protective bony plates and pairs of barbels around the mouth. These sensitive barbels help it locate food across the substrate, while the fish also regularly rises to the surface to gulp atmospheric air using its specialised intestine.

Leopard Corydoras C102 is peaceful, social and most confident when kept with its own kind. Groups spend much of their time exploring the bottom, resting among cover and sifting through the substrate, often becoming especially active during feeding or in the softer light of morning and evening.

In nature, corydoras inhabit shallow, slow-moving Amazonian streams, margins and flooded forest environments where leaf litter, submerged roots and sandy areas provide shelter. The C102 form remains a relatively uncommon specialist fish, and its exact scientific identity may be revised as these colour forms are studied more closely.

Corydoras sp. 'C102' is a South American corydoras from the western Amazon region. The exact collection locality associated with the C102 code is not consistently reported in the aquarium trade, so locality details should be treated with caution; it is generally regarded as a Peruvian or nearby upper-Amazon form.

A group of Leopard Corydoras C102 should have an aquarium of at least 60 litres, with a footprint of approximately 60 × 30 cm or larger. Use soft sand or very smooth, fine gravel to protect the barbels, and provide open bottom space for foraging alongside driftwood, rounded stones, hardy plants and shaded hiding places. Gentle water movement, efficient filtration and regular maintenance are important, while a secure lid is useful because corydoras can jump when startled or during surface-gulping excursions.

Up to about 5 cm (2 in) in total length. Females are typically slightly larger and broader-bodied than males, especially when mature.

Offer a varied diet based on sinking catfish pellets, tablets and granules, supplemented with frozen or live foods such as bloodworm, daphnia, mosquito larvae and brine shrimp. Their barbels are for finding food rather than for surviving on scraps, so make sure food reaches the bottom and that every fish receives a share. Blanched vegetables can occasionally add variety, although a quality, protein-rich sinking diet should form the mainstay.

Leopard Corydoras C102 are excellent community fish and can be housed with other peaceful South American species such as small tetras, pencilfish, peaceful rasboras, dwarf cichlids and other calm corydoras. Small peaceful livebearers and non-aggressive gouramis may also be suitable where water conditions overlap. Avoid large or boisterous cichlids, fin-nipping barbs, aggressive bottom-dwellers and fish that may compete intensely for food. They should not be kept with species likely to harass them or swallow them.

Leopard Corydoras C102 are egg-scattering spawners that can be encouraged to breed in a mature, well-maintained aquarium. Condition a group with plenty of varied, protein-rich foods, then stimulate spawning with a substantial water change using slightly cooler, clean water. A female carries adhesive eggs between her pelvic fins before placing them on aquarium glass, plants or other smooth surfaces, while males fertilise them. Remove the adults or protect the eggs from tankmates, as the eggs may be eaten. Hatching generally takes around three to five days, with fry becoming free-swimming shortly afterwards and requiring very small foods such as infusoria or finely powdered fry food.

Females are usually larger, deeper-bodied and noticeably broader when viewed from above. Males tend to be smaller and slimmer, with a more streamlined profile; the difference is most apparent in mature, well-conditioned fish.
