Can Banded Archerfish (Brackish) and Loxozonus Corydoras (C079/C082) Live Together?

Banded Archerfish (Brackish) is a moderately assertive species (6/10), while Loxozonus Corydoras (C079/C082) is peaceful (0/10). This notable difference means Banded Archerfish (Brackish) may occasionally assert dominance over Loxozonus Corydoras (C079/C082).

Large aggression gap (6 points) between Banded Archerfish (Brackish) and Loxozonus Corydoras (C079/C082) increases stress risk for the more peaceful fish.

In terms of spatial distribution, Banded Archerfish (Brackish) prefers the Top (Surface) zone, whereas Loxozonus Corydoras (C079/C082) 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 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 7.2. 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 Loxozonus Corydoras (C079/C082) 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 Loxozonus Corydoras (C079/C082) 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), 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.

Banded Archerfish (Brackish) and Loxozonus Corydoras (C079/C082) 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.
