Can Bronze Corydoras and Horei Cichlid Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 4, 2026
Not Recommended

Bronze Corydoras and Horei Cichlid 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.

Can your tank handle Bronze Corydoras and Horei Cichlid?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Bronze Corydoras is a peaceful species (1/10), while Horei Cichlid is semi-aggressive (8/10). This notable difference means Horei Cichlid may occasionally assert dominance over Bronze Corydoras.

Large aggression gap (7 points) between Bronze Corydoras and Horei Cichlid increases stress risk for the more peaceful fish.

Bronze Corydoras and Horei Cichlid 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.

Water Parameters

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Bronze Corydoras (6–7.5) and Horei Cichlid (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bronze Corydoras and Horei Cichlid together, plan for an aquarium of at least 208 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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). 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.

Why This Pairing Usually Fails in Practice

Bronze Corydoras and Horei Cichlid are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Frequently Asked Questions

Can Bronze Corydoras and Horei Cichlid 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 Horei Cichlid need?

A minimum of 208 litres (tank length at least 120 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 Horei Cichlid together?

Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.

Are Bronze Corydoras or Horei Cichlid aggressive?

Bronze Corydoras is peaceful (1/10) and Horei Cichlid is semi-aggressive (8/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Bronze Corydoras and Horei Cichlid need?

Their pH requirements do not overlap. Bronze Corydoras prefers 6–7.5, while Horei Cichlid needs 7.8–9. This makes them incompatible in the same water chemistry.

How do I manage Horei Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Horei Cichlid 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.
