Can Licorice Gourami and Platy Live Together?

Both Licorice Gourami and Platy are peaceful species with an aggression score of 2/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Licorice Gourami and Platy 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

The safe temperature window for both species falls between 22°C and 26°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

The pH requirements of Licorice Gourami (3–6) and Platy (7–8.2) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Licorice Gourami needs 0–4 dGH while Platy requires 10–25 dGH.

To house Licorice Gourami and Platy together, plan for an aquarium of at least 38 litres with a minimum length of 45 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding), Established Algae (Otocinclus). 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.

Licorice Gourami and Platy are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Feeding time deserves special attention with this pairing. Platy is an aggressive eater that may prevent Licorice Gourami from getting enough food.

Because Platy is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Licorice Gourami receives an adequate share.
