Corydoras Catfish Care Guide
Complete care guide for Corydoras catfish covering species, tank setup, school size, feeding, breeding, and why they are ideal community fish.
Housing and Enclosure
Corydoras need a minimum 20-gallon aquarium with a soft, sandy substrate — gravel can damage their sensitive barbels. Maintain temperatures of 72-78°F and provide gentle filtration. They are social and must be kept in groups of at least 6 of the same species. Include caves, driftwood, and plants for shelter.
Diet and Nutrition
Feed sinking pellets or wafers designed for bottom feeders as the staple diet. Supplement with frozen bloodworms, brine shrimp, and blanched vegetables. Corydoras are not effective algae eaters — they need dedicated feeding, not just leftovers. Feed in the evening when they are most active.
Health and Veterinary Care
Common corydoras health issues include barbel erosion (from rough substrate or poor water quality), ich, and bacterial infections. They are sensitive to salt and many medications — use half doses of most treatments. Maintain pristine water quality with regular changes and a sandy substrate.
Common Health Issues
- water chemistry imbalance: Often caused by inadequate UVB lighting or calcium supplementation
- Respiratory infections: Usually linked to incorrect temperature or humidity
- Parasites: Both internal and external parasites can affect exotic pets
- Nutritional deficiencies: Result from improper or monotonous diets
- Stress-related illness: Caused by improper housing, handling, or environmental factors
stocking compatibility and stress reduction
- Allow new pets to acclimate to their enclosure before handling
- Learn proper handling techniques specific to your pet's species
- Start with short handling sessions and gradually increase duration
- Wash hands before and after handling to prevent disease transmission
- Respect your pet's signals — not all exotic pets enjoy being handled
Are corydoras good for beginner fish keepers?
Some exotic pets are excellent for beginners (leopard geckos, corn snakes, budgies, betta fish) while others require advanced experience (chameleons, macaws, saltwater aquariums). Research thoroughly before committing.
How much do exotic pets cost to care for?
Initial setup costs (enclosure, lighting, heating) are usually the largest expense, ranging from $100-$1,000+. Ongoing costs for food, substrate, and veterinary care typically run $30-$100/month.
