Can Bearded Cory and Flagtail Cory (Mrs Schwartz's Cory) Live Together?

Bearded Cory is a peaceful species (2/10), while Flagtail Cory (Mrs Schwartz's Cory) is peaceful (1/10). This modest difference means Bearded Cory may occasionally assert dominance over Flagtail Cory (Mrs Schwartz's Cory).

Bearded Cory and Flagtail Cory (Mrs Schwartz's 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 Bearded Cory (16–23°C) and Flagtail Cory (Mrs Schwartz's Cory) (24–28°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6 and 7.4. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 2–12 dGH. Regular testing will ensure conditions stay within this range.

To house Bearded Cory and Flagtail Cory (Mrs Schwartz's Cory) together, plan for an aquarium of at least 110 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), 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.

Bearded Cory and Flagtail Cory (Mrs Schwartz's 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.
