Can Licorice Gourami and Tire Track Eel Live Together?

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

Licorice Gourami and Tire Track Eel both frequent the 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.

There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

Worth noting: Tire Track Eel is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Tire Track Eel is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 22°C and 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Licorice Gourami (3–6) and Tire Track Eel (6.5–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Licorice Gourami needs 0–4 dGH while Tire Track Eel requires 5–15 dGH.

To house Licorice Gourami and Tire Track Eel together, plan for an aquarium of at least 680 litres with a minimum length of 180 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), Smooth Gravel (Sensitive Barbels). 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 Tire Track Eel 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. Tire Track Eel is a known shrimp eater and may prey on small invertebrates or nano fish like Licorice Gourami.
