Can Black Ocellatus and Panda Corydoras Live Together?
Black Ocellatus and Panda Corydoras 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 Black Ocellatus and Panda Corydoras?
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
Black Ocellatus is a semi-aggressive species (7/10), while Panda Corydoras is peaceful (0/10). This notable difference means Black Ocellatus may occasionally assert dominance over Panda Corydoras.
Large aggression gap (7 points) between Black Ocellatus and Panda Corydoras increases stress risk for the more peaceful fish.
Black Ocellatus and Panda Corydoras 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 23°C and 25°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.
The pH requirements of Black Ocellatus (7.5–9) and Panda Corydoras (6–7.4) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 8–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Black Ocellatus and Panda Corydoras together, plan for an aquarium of at least 54 litres with a minimum length of 60 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), Shells (Breeding/Hiding). 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.

Frequently Asked Questions
Can Black Ocellatus and Panda Corydoras live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Black Ocellatus and Panda Corydoras need?
A minimum of 54 litres (tank length at least 60 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 Black Ocellatus and Panda Corydoras together?
Keep the aquarium between 23°C and 25°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.
Are Black Ocellatus or Panda Corydoras aggressive?
Black Ocellatus is semi-aggressive (7/10) and Panda Corydoras is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Black Ocellatus and Panda Corydoras need?
Their pH requirements do not overlap. Black Ocellatus prefers 7.5–9, while Panda Corydoras needs 6–7.4. This makes them incompatible in the same water chemistry.
How do I manage Black Ocellatus's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Black Ocellatus 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.
