Can African Pipefish and Banded Archerfish (Brackish) Live Together?

African Pipefish 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 African Pipefish.

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

In terms of spatial distribution, African Pipefish 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: Banded Archerfish (Brackish) is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

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.

To house African Pipefish and Banded Archerfish (Brackish) 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.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Plants - Densely covered, Sand (Sifters), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. African Pipefish and Banded Archerfish (Brackish) need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.
