Pepperd Cory

Overview

The Peppered Cory (Corydoras paleatus) is one of the hardiest and most beginner-friendly bottom-dwelling catfish. Their charming personality, group behaviour, and ability to clean up leftover food make them essential community fish.

Water Parameters

• Temperature: 18–25°C (64–77°F); tolerates cooler water
• pH: 6.0–7.5
• Hardness: 5–18 dGH (very adaptable)

Tank Setup

• Minimum tank size: 60 litres for 4+
• Substrate: Sand or very fine gravel essential — they have delicate barbels that can be damaged by sharp substrate
• Decor: Driftwood, plants; open areas for group resting
• Note: They are social and must be kept in groups of 4+

Diet

• Base: Sinking pellets, wafer foods
• Treats: Frozen bloodworms, brine shrimp, daphnia
• Note: They are bottom feeders — ensure food reaches them; feed after lights out for best results

Temperament & Tank Mates

• Temperament: Peaceful, social, active during the day
• Best companions: All peaceful community fish — tetras, rasboras, gouramis, shrimp (adults)
• Schooling: Groups of 6+; they rest together in piles on the substrate

Breeding

• Difficulty: Easy; they breed readily with cool water changes
• Process: "T-position" embrace; eggs laid on leaves and glass; remove parents
• Trigger: Large water change with cooler water often triggers spawning

Common Issues

• Sharp substrate damages barbels — use sand only
• Prone to whirling disease (Columnaris) in poor water quality
• Nocturnal at times — may hide during the day
• Lifespan: 5–7 years
