Behaviour & Temperament

Bronze Corydoras is a peaceful species (1/10), while Zebra Danio is generally mild-mannered (3/10). This modest difference means Zebra Danio may occasionally assert dominance over Bronze Corydoras.

In terms of spatial distribution, Bronze Corydoras prefers the Bottom (Substrate) zone, whereas Zebra Danio occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Zebra Danio is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 22°C and 26°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bronze Corydoras and Zebra Danio together, plan for an aquarium of at least 72 litres with a minimum length of 60 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Bronze Corydoras and Zebra Danio live together?

Yes. Bronze Corydoras and Zebra Danio are considered ideal tank mates. Their water parameters, temperaments, and behaviour profiles are well matched for a community aquarium.

What size tank do Bronze Corydoras and Zebra Danio need?

A minimum of 72 litres (tank length at least 60 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Bronze Corydoras and Zebra Danio together?

Keep the aquarium between 22°C and 26°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.

Are Bronze Corydoras or Zebra Danio aggressive?

Bronze Corydoras is peaceful (1/10) and Zebra Danio is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Bronze Corydoras and Zebra Danio need?

Both species overlap in the 6.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Zebra Danio nip Bronze Corydoras's fins?

Zebra Danio is a known fin nipper. If Bronze Corydoras has long or flowing fins, there is a real risk of fin damage. Keeping Zebra Danio in a larger group can help redirect nipping behaviour toward conspecifics.
