Can Bearded Cory and Pseudotropheus Acei Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 7, 2026
Not Recommended

Bearded Cory and Pseudotropheus Acei are not recommended as tank mates due to no temperature overlap and 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 Bearded Cory and Pseudotropheus Acei?

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

Bearded Cory is a peaceful species (2/10), while Pseudotropheus Acei is generally mild-mannered (4/10). This modest difference means Pseudotropheus Acei may occasionally assert dominance over Bearded Cory.

Bearded Cory and Pseudotropheus Acei 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

There is no temperature overlap between Bearded Cory (16–23°C) and Pseudotropheus Acei (24–28°C). This fundamental mismatch makes long-term cohabitation impractical.

The pH requirements of Bearded Cory (6–7.4) and Pseudotropheus Acei (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 Bearded Cory and Pseudotropheus Acei 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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

Bearded Cory and Pseudotropheus Acei 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 Bearded Cory and Pseudotropheus Acei live together?

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.

What size tank do Bearded Cory and Pseudotropheus Acei 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 Bearded Cory and Pseudotropheus Acei together?

Unfortunately, there is no temperature range that satisfies both species. Bearded Cory requires 16–23°C, while Pseudotropheus Acei needs 24–28°C.

Are Bearded Cory or Pseudotropheus Acei aggressive?

Bearded Cory is peaceful (2/10) and Pseudotropheus Acei is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Bearded Cory and Pseudotropheus Acei need?

Their pH requirements do not overlap. Bearded Cory prefers 6–7.4, while Pseudotropheus Acei needs 7.8–8.6. This makes them incompatible in the same water chemistry.

How do I manage Pseudotropheus Acei's territorial behaviour?

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