Can Bamboo Shrimp and Banded Archerfish (Brackish) Live Together?

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

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

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

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

Worth noting: Bamboo Shrimp is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 15–15 dGH. Regular testing will ensure conditions stay within this range.

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 Bamboo Shrimp and Banded Archerfish (Brackish) 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: Driftwood (Digestion/Hiding), Sand (Sifters). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.
