Can Snakehead Fighter and Telmatochromis dhonti Live Together?

Snakehead Fighter is a peaceful species (2/10), while Telmatochromis dhonti is semi-aggressive (8/10). This notable difference means Telmatochromis dhonti may occasionally assert dominance over Snakehead Fighter.

Large aggression gap (6 points) between Snakehead Fighter and Telmatochromis dhonti increases stress risk for the more peaceful fish.

Snakehead Fighter and Telmatochromis dhonti 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.

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species.

Worth noting: Snakehead Fighter is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Snakehead Fighter (4–6.5) and Telmatochromis dhonti (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Snakehead Fighter needs 1–5 dGH while Telmatochromis dhonti requires 10–25 dGH.

To house Snakehead Fighter and Telmatochromis dhonti together, plan for an aquarium of at least 120 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, Sand (Sifters), Shells (Breeding/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.

Snakehead Fighter and Telmatochromis dhonti 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.
