Can your tank handle Licorice Gourami and Long-Finned African Tetra?

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

Both Licorice Gourami and Long-Finned African Tetra 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 Long-Finned African Tetra 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.

Worth noting: Long-Finned African Tetra 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 Long-Finned African Tetra requires 5–19 dGH.

Tank Setup

To house Licorice Gourami and Long-Finned African Tetra together, plan for an aquarium of at least 200 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). Meeting these requirements will help both species thrive.

Licorice Gourami prefers Low (Still Water) flow while Long-Finned African Tetra needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Why This Pairing Usually Fails in Practice

Licorice Gourami and Long-Finned African Tetra 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.

Diet & Feeding

Feeding time deserves special attention with this pairing. Long-Finned African Tetra is an aggressive eater that may prevent Licorice Gourami from getting enough food.

Because Long-Finned African Tetra 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.

What water temperature is best for Licorice Gourami and Long-Finned African Tetra 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 Long-Finned African Tetra aggressive?

Licorice Gourami is peaceful (2/10) and Long-Finned African Tetra is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Licorice Gourami and Long-Finned African Tetra need?

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