Can Fairy Cichlid (Brichardi) and Three Spot Gourami (Blue/Gold/Opaline) Live Together?

Fairy Cichlid (Brichardi) is a semi-aggressive species (8/10), while Three Spot Gourami (Blue/Gold/Opaline) is moderately assertive (6/10). This modest difference means Fairy Cichlid (Brichardi) may occasionally assert dominance over Three Spot Gourami (Blue/Gold/Opaline).

Fairy Cichlid (Brichardi) 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.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.

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 Fairy Cichlid (Brichardi) and Three Spot Gourami (Blue/Gold/Opaline) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

The safe temperature window for both species falls between 23°C and 27°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 8 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 10–25 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house Fairy Cichlid (Brichardi) and Three Spot Gourami (Blue/Gold/Opaline) together, plan for an aquarium of at least 132 litres with a minimum length of 90 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Plants - Floating. 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.
