Behaviour & Temperament

Scat (Brackish) is a generally mild-mannered species (4/10), while Three Spot Gourami (Blue/Gold/Opaline) is moderately assertive (6/10). This modest difference means Three Spot Gourami (Blue/Gold/Opaline) may occasionally assert dominance over Scat (Brackish).

Scat (Brackish) and Three Spot Gourami (Blue/Gold/Opaline) both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Water Parameters

The safe temperature window for both species falls between 22°C and 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 12–25 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. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Scat (Brackish) and Three Spot Gourami (Blue/Gold/Opaline) together, plan for an aquarium of at least 540 litres with a minimum length of 150 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Plants - Densely covered, Plants - Floating. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Scat (Brackish) is a plant destroyer, which conflicts with Three Spot Gourami (Blue/Gold/Opaline)'s requirement for live plants. Compromise where possible or prioritise the more critical need.

Scat (Brackish) prefers High (River/Stream) flow while Three Spot Gourami (Blue/Gold/Opaline) needs Low (Still Water) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Frequently Asked Questions

Can Scat (Brackish) and Three Spot Gourami (Blue/Gold/Opaline) live together?

No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.

What size tank do Scat (Brackish) and Three Spot Gourami (Blue/Gold/Opaline) need?

A minimum of 540 litres (tank length at least 150 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Scat (Brackish) and Three Spot Gourami (Blue/Gold/Opaline) together?

Keep the aquarium between 22°C and 28°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Scat (Brackish) or Three Spot Gourami (Blue/Gold/Opaline) aggressive?

Scat (Brackish) is generally mild-mannered (4/10) and Three Spot Gourami (Blue/Gold/Opaline) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Scat (Brackish) and Three Spot Gourami (Blue/Gold/Opaline) need?

Both species overlap in the 7.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Scat (Brackish) nip Three Spot Gourami (Blue/Gold/Opaline)'s fins?

Scat (Brackish) is a known fin nipper. If Three Spot Gourami (Blue/Gold/Opaline) has long or flowing fins, there is a real risk of fin damage. Keeping Scat (Brackish) in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Three Spot Gourami (Blue/Gold/Opaline)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Three Spot Gourami (Blue/Gold/Opaline) 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.
