Can Banded Archerfish (Brackish) and Silver Tiger Perch (American Tigerfish) Live Together?

Banded Archerfish (Brackish) is a moderately assertive species (6/10), while Silver Tiger Perch (American Tigerfish) is semi-aggressive (7/10). This modest difference means Silver Tiger Perch (American Tigerfish) may occasionally assert dominance over Banded Archerfish (Brackish).

In terms of spatial distribution, Banded Archerfish (Brackish) prefers the Top (Surface) zone, whereas Silver Tiger Perch (American Tigerfish) occupies the Middle (Open Water) and Bottom (Substrate) zones. 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.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Banded Archerfish (Brackish) and Silver Tiger Perch (American Tigerfish) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

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 7.5 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 15–30 dGH. Regular testing will ensure conditions stay within this range.

To house Banded Archerfish (Brackish) and Silver Tiger Perch (American Tigerfish) together, plan for an aquarium of at least 650 litres with a minimum length of 180 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: 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Banded Archerfish (Brackish) and Silver Tiger Perch (American Tigerfish) 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.
