Can your tank handle Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara)?

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

Loxozonus Corydoras (C079/C082) is a peaceful species (0/10), while Peacock Cichlid (Aulonocara) is moderately assertive (6/10). This notable difference means Peacock Cichlid (Aulonocara) may occasionally assert dominance over Loxozonus Corydoras (C079/C082).

Large aggression gap (6 points) between Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara) increases stress risk for the more peaceful fish.

Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara) 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 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Loxozonus Corydoras (C079/C082) (6–7.2) and Peacock Cichlid (Aulonocara) (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara) together, plan for an aquarium of at least 200 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), Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara) 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 Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara) live together?

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

What size tank do Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara) need?

A minimum of 200 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 Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara) together?

Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Loxozonus Corydoras (C079/C082) or Peacock Cichlid (Aulonocara) aggressive?

Loxozonus Corydoras (C079/C082) is peaceful (0/10) and Peacock Cichlid (Aulonocara) is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Loxozonus Corydoras (C079/C082) and Peacock Cichlid (Aulonocara) need?

Their pH requirements do not overlap. Loxozonus Corydoras (C079/C082) prefers 6–7.2, while Peacock Cichlid (Aulonocara) needs 7.8–8.6. This makes them incompatible in the same water chemistry.

How do I manage Peacock Cichlid (Aulonocara)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Peacock Cichlid (Aulonocara) 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.
