Can Altolamprologus Compressiceps and Bearded Cory Live Together?

Altolamprologus Compressiceps is a moderately assertive species (6/10), while Bearded Cory is peaceful (2/10). This notable difference means Altolamprologus Compressiceps may occasionally assert dominance over Bearded Cory.

Altolamprologus Compressiceps and Bearded Cory 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

There is no temperature overlap between Altolamprologus Compressiceps (24–27°C) and Bearded Cory (16–23°C). This fundamental mismatch makes long-term cohabitation impractical.

The pH requirements of Altolamprologus Compressiceps (7.8–9) and Bearded Cory (6–7.4) 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.

To house Altolamprologus Compressiceps and Bearded Cory together, plan for an aquarium of at least 150 litres with a minimum length of 90 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 moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Altolamprologus Compressiceps and Bearded Cory 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.
