Corydoras similis (Smudge Spot Corydoras)
Subtle, elegant cory best suited to stable, established aquariums
Quick Facts
- Size: ~5–6 cm
- Tank size: 50L+ recommended
- Difficulty: 🟡 Moderate
- Temperament: Peaceful
- Best kept: Groups (5+)
- Plant safe: Yes
Is this for you?
✔️ Good if:
- You want a more refined or less common Corydoras
- You have an established, stable aquarium
- You keep peaceful community fish
- You are comfortable maintaining consistent water quality
❌ Avoid if:
- Your tank is newly set up
- You want a “set and forget” beginner fish
- You plan to keep just one
- You keep aggressive or fast-feeding fish
Why this fish?
Corydoras similis is appreciated for its clean body pattern and distinctive dark “smudge” marking near the dorsal area.
It offers the same peaceful and social behaviour as other corydoras, but is better suited to stable environments where water quality is consistent.
Common mistakes
- Adding to immature tanks → higher stress and losses
- Keeping them alone instead of in groups
- Underfeeding due to “bottom feeder” assumptions
- Keeping with aggressive or highly competitive fish
- Inconsistent water quality or sudden changes
Care made simple
- Temperature: 22–26°C
- Diet: Sinking pellets, wafers, frozen foods
- Group size: 5+ recommended
- Substrate: Soft sand preferred
- Water: Clean, stable, well-maintained
Pair with
- Sinking cory pellets or wafers
- Fine sand substrate
- Driftwood and plants
- Peaceful tetra, rasbora, or nano fish
This species does best when water conditions are stable and consistent. Most issues come from fluctuations or immature tanks rather than difficulty of care.
FAQ
Is Corydoras similis good for beginners?
It can be kept by beginners with an established tank, but it is less forgiving than common corydoras like paleatus or aeneus.
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 along the bottom 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 such as bloodworms or brine shrimp.
