Introduction:
The Hi-Fin Peppered Cory (Corydoras paleatus) is a delightful variation of the popular Peppered Corydoras, characterized by its distinctive long dorsal fin.

1. Natural Habitat and Behavior
Hi-Fin Peppered Corys are native to South America, specifically in the cool, slow-moving rivers and streams of Argentina, Brazil, and Uruguay. They inhabit areas with sandy or muddy substrates and plenty of aquatic vegetation. These catfish are social, often seen foraging in groups, and display endearing behaviors like “winking” with their pectoral fins and resting together during quiet moments.
2. Aquarium Setup
- Tank Size: A minimum of 20 gallons (75 liters) is recommended for a group of 5–6 individuals.
- Substrate: Fine sand or smooth gravel to protect their delicate barbels.
- Decor: Include driftwood, plants, and caves to create hiding spots and mimic their natural environment.
- Water Conditions:
- Temperature: 68–75°F (20–24°C)
- pH: 6.0–7.5
- Hardness: 2–12 dGH
- Filtration: Moderate water flow and excellent filtration to maintain water quality.
- Lighting: Low to moderate lighting enhances their comfort and promotes a natural habitat.
3. Diet and Feeding
Hi-Fin Peppered Corys are omnivorous scavengers with a preference for sinking foods.
- Preferred Foods: Sinking pellets or wafers designed for bottom feeders.
- Supplemental Foods: Live or frozen bloodworms, brine shrimp, and daphnia.
- Vegetable Matter: Blanched zucchini, spinach, or algae wafers.
- Feeding Tips: Feed small portions twice daily, ensuring food reaches the bottom of the tank.
4. Compatibility with Other Fish
- Tank Mates: Peaceful fish like tetras, rasboras, guppies, and other small community species.
- Avoid: Large or aggressive species that might outcompete them for food or cause stress.
- Behavior: Highly social, Hi-Fin Peppered Corys thrive in groups of 5 or more. They are non-aggressive and coexist well with other bottom dwellers like loaches.
5. Common Challenges and Tips
- Barbel Health: Sharp substrates or poor water quality can damage their barbels. Use fine sand and maintain clean water.
- Shyness: Ensure they are kept in groups to reduce stress and encourage natural behaviors.
- Oxygenation: They occasionally surface to gulp air, so ensure good aeration and surface agitation.
- Water Temperature: Avoid high temperatures, as they prefer cooler conditions compared to many tropical species.
