Behaviour & Temperament

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

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

Loxozonus Corydoras (C079/C082) and Sunset Hap 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 Sunset Hap (7.6–8.6) 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 Sunset Hap together, plan for an aquarium of at least 400 litres with a minimum length of 150 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 Sunset Hap 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Loxozonus Corydoras (C079/C082) and Sunset Hap.

Frequently Asked Questions

Can Loxozonus Corydoras (C079/C082) and Sunset Hap 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 Sunset Hap need?

A minimum of 400 litres (tank length at least 150 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 Sunset Hap 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 Sunset Hap aggressive?

Loxozonus Corydoras (C079/C082) is peaceful (0/10) and Sunset Hap 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 Sunset Hap need?

Their pH requirements do not overlap. Loxozonus Corydoras (C079/C082) prefers 6–7.2, while Sunset Hap needs 7.6–8.6. This makes them incompatible in the same water chemistry.

How do I manage Sunset Hap's territorial behaviour?

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