Can Frontosa and Tire Track Eel Live Together?

🔴Not Recommended

Frontosa and Tire Track Eel are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament

Frontosa is a moderately assertive species (5/10), while Tire Track Eel is moderately assertive (6/10). This modest difference means Tire Track Eel may occasionally assert dominance over Frontosa.

Frontosa 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.

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.

Water Parameters

The safe temperature window for both species falls between 23°C and 27°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Frontosa (8–9) and Tire Track Eel (6.5–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 12–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Frontosa and Tire Track Eel together, plan for an aquarium of at least 816 litres with a minimum length of 180 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Frontosa and Tire Track Eel live together?

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

What size tank do Frontosa and Tire Track Eel need?

A minimum of 816 litres (tank length at least 180 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 Frontosa and Tire Track Eel together?

Keep the aquarium between 23°C and 27°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Frontosa or Tire Track Eel aggressive?

Frontosa is moderately assertive (5/10) and Tire Track Eel is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Frontosa and Tire Track Eel need?

Their pH requirements do not overlap. Frontosa prefers 8–9, while Tire Track Eel needs 6.5–7.5. This makes them incompatible in the same water chemistry.

How do I manage Frontosa's territorial behaviour?

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

Does Tire Track Eel being nocturnal affect compatibility?

Tire Track Eel is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Tire Track Eel during evening hours.
