Origin and Distribution

Peppered corydoras are native to slow-moving rivers, streams, and ponds in South America. They are commonly found in areas with dense vegetation and sandy or muddy substrates, providing them with natural cover and feeding grounds.

Colors and Markings

Peppered corydoras display a base color of light gray or beige with distinctive dark, mottled spots resembling a “peppered” appearance. Their undersides are lighter, and they feature a short pair of barbels around their mouths for foraging.

Tankmates

Peppered corydoras are peaceful bottom-dwellers, making them suitable for community tanks. Ideal tankmates include:

• Small tetras (like neon or cardinal tetras)
• Rasboras
• Dwarf gouramis
• Other peaceful bottom-dwellers like kuhli loaches and smaller plecos

Avoid aggressive or overly large species that may outcompete or harm these gentle fish.

Care

Peppered corydoras thrive in tanks with a soft substrate such as sand to protect their sensitive barbels. A well-decorated tank with plants, driftwood, and hiding spots is essential. They prefer stable water conditions with moderate flow. Keep the tank clean and free of decaying matter, as they are sensitive to poor water quality.

Maintain the following conditions:

• pH: 6.0–7.5
• Hardness: Up to 15 dGH
• Temperature: 68–78°F (20–26°C)

Diet and Feeding

As omnivores, peppered corydoras enjoy a varied diet that includes sinking pellets, algae wafers, and occasional live or frozen foods like bloodworms, brine shrimp, and daphnia. Ensure their food reaches the tank bottom, as they won’t compete with mid-level or surface feeders.

Gender Differences

Females are generally larger and rounder in the abdomen, especially when ready to spawn. Males tend to be slimmer and slightly smaller in size.

Breeding

Peppered corydoras are relatively easy to breed. Set up a dedicated breeding tank with soft water and a temperature of 75–78°F (24–26°C). Trigger spawning by performing small, cooler water changes to mimic their natural rainy season.

Females lay adhesive eggs on smooth surfaces like glass or broad plant leaves. Eggs hatch in about 3–5 days, and fry can be fed infusoria or finely crushed flake food before transitioning to baby brine shrimp.
