Can Licorice Gourami and Pumpkinseed Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Licorice Gourami and Pumpkinseed are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Licorice Gourami and Pumpkinseed?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Licorice Gourami is a peaceful species (2/10), while Pumpkinseed is semi-aggressive (7/10). This notable difference means Pumpkinseed may occasionally assert dominance over Licorice Gourami.

Licorice Gourami and Pumpkinseed both frequent the Middle (Open Water) and Bottom (Substrate) 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Water Parameters

The safe temperature window for both species falls between 22°C and 25°C. Aim for the midpoint of this range (around 23.5°C) for optimal comfort.

The pH requirements of Licorice Gourami (3–6) and Pumpkinseed (6.5–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Licorice Gourami needs 0–4 dGH while Pumpkinseed requires 5–20 dGH.

Tank Setup

To house Licorice Gourami and Pumpkinseed together, plan for an aquarium of at least 280 litres with a minimum length of 120 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), Sand (Sifters). 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.

Why This Pairing Usually Fails in Practice

Licorice Gourami and Pumpkinseed 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.

Frequently Asked Questions

Can Licorice Gourami and Pumpkinseed live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Licorice Gourami and Pumpkinseed need?

A minimum of 280 litres (tank length at least 120 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 Licorice Gourami and Pumpkinseed together?

Keep the aquarium between 22°C and 25°C. A target of around 23.5°C sits comfortably within both species' preferred ranges.

Are Licorice Gourami or Pumpkinseed aggressive?

Licorice Gourami is peaceful (2/10) and Pumpkinseed is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Licorice Gourami and Pumpkinseed need?

Their pH requirements do not overlap. Licorice Gourami prefers 3–6, while Pumpkinseed needs 6.5–8.5. This makes them incompatible in the same water chemistry.

How do I manage Pumpkinseed's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Pumpkinseed 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.
