Breeding Corydoras leopardus

Breeding the long-snouted Corydoras leopardus: water parameters, the documented genus T-position spawning pattern, and fry care.

Overview

Corydoras leopardus (also placed in the genus Brochis) is a callichthyid catfish of the western Amazon River basin. FishBase records a maximum length of about 6.1 cm SL, with a tolerance of pH 6.0-8.0, hardness 2-25 dH, and 22-25 C, and notes facultative air-breathing. It has a longer, more pointed snout and grows larger than the very similar three-line cory (formerly C. trilineatus), with which it is often confused. It is listed as Least Concern by the IUCN.

Breeding Setup

Within the FishBase tolerances above, soft to moderately hard, slightly acidic to neutral water is appropriate. As for related Corydoras, flat surfaces such as the aquarium glass, fine-leaved plants, or spawning mops serve as deposition sites, and a thin sand layer suits the fry.

Spawning Behaviour & Trigger

Note: species-specific spawning data for C. leopardus was not found in the consulted whitelisted sources, so the following reflects the documented breeding pattern for the genus rather than verified observations of this species. Corydoras typically spawn after a large cooler water change combined with increased oxygenation and flow; the female cups a small number of eggs between her pelvic fins in the so-called T-position while the male fertilises them, and the eggs are then attached to a chosen surface.

Egg & Fry Care

Following the genus pattern, eggs typically hatch within a few days; once fry absorb their yolk sacs they take small live foods such as microworm and brine shrimp (Artemia) nauplii. Excellent water quality is essential. These details follow the general Corydoras pattern and are not species-specific records for C. leopardus.
