Can Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) Live Together?
Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) 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.
At a Glance
Can your tank handle Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082)?
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
Cobalt Blue Zebra is a semi-aggressive species (8/10), while Loxozonus Corydoras (C079/C082) is peaceful (0/10). This notable difference means Cobalt Blue Zebra may occasionally assert dominance over Loxozonus Corydoras (C079/C082).
Large aggression gap (8 points) between Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) increases stress risk for the more peaceful fish.
Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) 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 Cobalt Blue Zebra (7.8–8.6) and Loxozonus Corydoras (C079/C082) (6–7.2) 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 Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) 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. 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
Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) 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 Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) 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 Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) 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 Cobalt Blue Zebra or Loxozonus Corydoras (C079/C082) aggressive?
Cobalt Blue Zebra is semi-aggressive (8/10) and Loxozonus Corydoras (C079/C082) is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Cobalt Blue Zebra and Loxozonus Corydoras (C079/C082) need?
Their pH requirements do not overlap. Cobalt Blue Zebra prefers 7.8–8.6, while Loxozonus Corydoras (C079/C082) needs 6–7.2. This makes them incompatible in the same water chemistry.
How do I manage Cobalt Blue Zebra's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Cobalt Blue Zebra 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.
