Can Licorice Gourami and Paradise Fish Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Not Recommended

Licorice Gourami and Paradise Fish are not recommended as tank mates due to 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 Paradise Fish?

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 Paradise Fish is semi-aggressive (8/10). This notable difference means Paradise Fish may occasionally assert dominance over Licorice Gourami.

Large aggression gap (6 points) between Licorice Gourami and Paradise Fish increases stress risk for the more peaceful fish.

Licorice Gourami and Paradise Fish 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Paradise Fish is a known jumper, so a tight-fitting lid is essential.

Water Parameters

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.

Both fish can tolerate a pH between 6 and 6. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Licorice Gourami needs 0–4 dGH while Paradise Fish requires 5–30 dGH.

Tank Setup

To house Licorice Gourami and Paradise Fish together, plan for an aquarium of at least 75 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding). 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 Paradise Fish 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 Paradise Fish 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 Paradise Fish need?

A minimum of 75 litres (tank length at least 80 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 Paradise Fish together?

Keep the aquarium between 22°C and 26°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.

Are Licorice Gourami or Paradise Fish aggressive?

Licorice Gourami is peaceful (2/10) and Paradise Fish is semi-aggressive (8/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Licorice Gourami and Paradise Fish need?

Both species overlap in the 6–6 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Paradise Fish nip Licorice Gourami's fins?

Paradise Fish is a known fin nipper. If Licorice Gourami has long or flowing fins, there is a real risk of fin damage. Keeping Paradise Fish in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Paradise Fish's territorial behaviour?

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