- Neglecting water quality stability
Care made simple
- Temperature: 22–26°C
- Diet: Sinking pellets, wafers, frozen foods
- Group size: 5+ recommended

- Water: Clean, stable, well-maintained
Pair with

Compared to common corydoras, this species benefits more from stable water conditions. Most issues come from immature tanks rather than the fish itself.
FAQ
Is this a beginner fish?
It can be, but only in an established tank. It is less forgiving than common corydoras.
Can I keep just one?
No. Corydoras are social fish and should be kept in groups of at least 5.
Do they clean the tank?
No. They forage for food but still require proper feeding.
Do they need sand?
Soft sand is preferred to protect their barbels, though smooth substrate can also work.
What do they eat?
Sinking pellets, wafers, and frozen foods like bloodworms or brine shrimp.
