Can Bronze Corydoras and Frontosa Live Together?

🔴Not Recommended

Bronze Corydoras and Frontosa are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament

Bronze Corydoras is a peaceful species (1/10), while Frontosa is moderately assertive (5/10). This notable difference means Frontosa may occasionally assert dominance over Bronze Corydoras.

Bronze Corydoras and Frontosa both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Water Parameters

The safe temperature window for both species falls between 23°C and 27°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Bronze Corydoras (6–7.5) and Frontosa (8–9) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 12–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bronze Corydoras and Frontosa together, plan for an aquarium of at least 570 litres with a minimum length of 180 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 Frontosa live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Bronze Corydoras and Frontosa need?

A minimum of 570 litres (tank length at least 180 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 Frontosa together?

Keep the aquarium between 23°C and 27°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Bronze Corydoras or Frontosa aggressive?

Bronze Corydoras is peaceful (1/10) and Frontosa is moderately assertive (5/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Bronze Corydoras and Frontosa need?

Their pH requirements do not overlap. Bronze Corydoras prefers 6–7.5, while Frontosa needs 8–9. This makes them incompatible in the same water chemistry.

How do I manage Frontosa's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Frontosa space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
