Can Banded Archerfish (Brackish) and Bearded Cory Live Together?

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

In terms of spatial distribution, Banded Archerfish (Brackish) prefers the Top (Surface) zone, whereas Bearded Cory occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Banded Archerfish (Brackish) is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between Banded Archerfish (Brackish) (24–30°C) and Bearded Cory (16–23°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7 and 7.4. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Banded Archerfish (Brackish) needs 15–30 dGH while Bearded Cory requires 2–12 dGH.

Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.

To house Banded Archerfish (Brackish) and Bearded Cory together, plan for an aquarium of at least 300 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), 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.
