Can Banded Archerfish (Brackish) and Tambraparni Barb Live Together?
Banded Archerfish (Brackish) and Tambraparni Barb are not recommended as tank mates due to incompatible water types and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Banded Archerfish (Brackish) and Tambraparni Barb?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament
Banded Archerfish (Brackish) is a moderately assertive species (6/10), while Tambraparni Barb is generally mild-mannered (3/10). This modest difference means Banded Archerfish (Brackish) may occasionally assert dominance over Tambraparni Barb.
In terms of spatial distribution, Banded Archerfish (Brackish) prefers the Top (Surface) zone, whereas Tambraparni Barb occupies the Middle (Open Water) 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.
Water Parameters
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 7.5. 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 Tambraparni Barb requires 4–12 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.

Tank Setup
To house Banded Archerfish (Brackish) and Tambraparni Barb 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), Smooth Gravel (Sensitive Barbels). 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.
