Can Butterfly Goodeid and Licorice Gourami Live Together?

Butterfly Goodeid is a moderately assertive species (6/10), while Licorice Gourami is peaceful (2/10). This notable difference means Butterfly Goodeid may occasionally assert dominance over Licorice Gourami.

Butterfly Goodeid and Licorice Gourami 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.

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 Butterfly Goodeid (7–8.5) and Licorice Gourami (3–6) do not overlap, making it impossible to satisfy both species simultaneously.

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

To house Butterfly Goodeid and Licorice Gourami together, plan for an aquarium of at least 110 litres with a minimum length of 80 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: Established Algae (Otocinclus), Plants - lighly covered, Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Butterfly Goodeid is a plant destroyer, which conflicts with Licorice Gourami's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Butterfly Goodeid and Licorice Gourami 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.
