Can Dwarf Gourami and Frontosa Live Together?
Dwarf Gourami and Frontosa are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Behaviour & Temperament
Both Dwarf Gourami and Frontosa are moderately assertive species with an aggression score of 5/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Dwarf Gourami and Frontosa 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.
Water Parameters
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.
The pH requirements of Dwarf Gourami (6–7.5) and Frontosa (8–9) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 12–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Dwarf Gourami and Frontosa together, plan for an aquarium of at least 570 litres with a minimum length of 180 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: Plants - Densely covered, Plants - Floating, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions
Can Dwarf Gourami and Frontosa live together?▾
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Dwarf Gourami and Frontosa need?▾
A minimum of 570 litres (tank length at least 180 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 Dwarf Gourami and Frontosa together?▾
Keep the aquarium between 23°C and 27°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.
Are Dwarf Gourami or Frontosa aggressive?▾
Dwarf Gourami is moderately assertive (5/10) and Frontosa is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Dwarf Gourami and Frontosa need?▾
Their pH requirements do not overlap. Dwarf Gourami prefers 6–7.5, while Frontosa needs 8–9. This makes them incompatible in the same water chemistry.
How do I manage Dwarf Gourami's territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Dwarf Gourami 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.
