Can Banded Archerfish (Brackish) and Panda Corydoras Live Together?

Banded Archerfish (Brackish) is a moderately assertive species (6/10), while Panda Corydoras is peaceful (0/10). This notable difference means Banded Archerfish (Brackish) may occasionally assert dominance over Panda Corydoras.

Large aggression gap (6 points) between Banded Archerfish (Brackish) and Panda Corydoras increases stress risk for the more peaceful fish.

In terms of spatial distribution, Banded Archerfish (Brackish) prefers the Top (Surface) zone, whereas Panda Corydoras 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.

The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

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 Panda Corydoras 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 Panda Corydoras together, plan for an aquarium of at least 360 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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.
