Topick Aquarium Insight
Rare Corydoras-type fish are often described as difficult, but the real issue is usually not the species itself. The difference is often source, quarantine, conditioning, and adaptation.
A properly settled CW111 should be active, feeding consistently, and stable before sale. For rare Cory species, we focus on long-term success rather than rushing fish out immediately after arrival.
Behavior & Group Size
CW111 is a peaceful and social bottom-dwelling fish. We recommend keeping them in a group whenever possible, ideally 6 or more, to encourage natural activity and confidence.
Single individuals may survive, but they will not show the same natural behavior as a properly sized group.
Tank Setup
A clean, stable aquarium with soft substrate is strongly recommended.
- Fine sand substrate to protect barbels
- Driftwood, botanicals, or shaded areas for security
- Clean, oxygen-rich water
- Gentle to moderate flow
- Stable filtration with regular maintenance
Avoid sharp gravel or unstable new tanks. Like most Corydoras-type catfish, CW111 spends much of its time exploring and sifting the bottom.

- Peaceful dwarf cichlids
- Other Corydoras-type catfish
Avoid aggressive cichlids, large predatory fish, or overly competitive bottom feeders.

FAQ
Is CW111 Vulcan Cory beginner-friendly?
Not as a first Corydoras species. It is best for intermediate to advanced aquarists or collectors who already understand stable aquarium care.
How many CW111 should I keep?
We recommend keeping them in groups, ideally 6 or more, for better confidence and natural behavior.
Can CW111 live with community fish?
Yes. They are peaceful and can be kept with small to medium peaceful fish such as tetras, rasboras, and other calm community species.
What substrate is best?
Fine sand is strongly recommended. Sharp gravel can damage their barbels and reduce natural foraging behavior.
Why is proper quarantine important for rare Cory species?
Rare Corydoras-type fish may look fine shortly after arrival, but long-term success depends on stable feeding, digestion, and adaptation. Proper conditioning reduces delayed losses and improves long-term survival.
