Can Banded Archerfish (Brackish) and Banded Chromide Live Together?
Keeping Banded Archerfish (Brackish) and Banded Chromide together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 461 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Can your tank handle Banded Archerfish (Brackish) and Banded Chromide?
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 Banded Chromide is moderately assertive (5/10). This modest difference means Banded Archerfish (Brackish) may occasionally assert dominance over Banded Chromide.
In terms of spatial distribution, Banded Archerfish (Brackish) prefers the Top (Surface) zone, whereas Banded Chromide 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 Banded Chromide to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.
Water Parameters
The safe temperature window for both species falls between 24°C and 30°C. Aim for the midpoint of this range (around 27.0°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 15–25 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Banded Archerfish (Brackish) and Banded Chromide together, plan for an aquarium of at least 461 litres with a minimum length of 150 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), 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.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Banded Archerfish (Brackish) and Banded Chromide.

What water temperature is best for Banded Archerfish (Brackish) and Banded Chromide together?
Keep the aquarium between 24°C and 30°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.
Are Banded Archerfish (Brackish) or Banded Chromide aggressive?
Banded Archerfish (Brackish) is moderately assertive (6/10) and Banded Chromide is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Banded Archerfish (Brackish) and Banded Chromide need?
Both species overlap in the 7.5–8.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Banded Chromide's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Banded Chromide space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
