Expert Care Tips for Corydoras Catfish
- Mid-size tank: Corydoras Catfish needs 20+ gallons. Choose a tank at least 2× as long as the fish's adult size (2.8") for adequate swimming room.
- Tropical range: Keep Corydoras Catfish at 72–78°F. A 50W heater per 10 gallons is a safe rule of thumb for stable temperature.
- Adaptable pH range: Corydoras Catfish accepts pH 6.0–7.5. Most tap water falls within this range, but always test and acclimate slowly.
- Peaceful community fish: Corydoras Catfish works well in community tanks. Still, avoid housing with fish large enough to eat them — a 2.8" fish is vulnerable to anything with a mouth bigger than 2×.
- Acclimation: Always drip-acclimate Corydoras Catfish over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
