Behaviour & Temperament

Bala Shark is a generally mild-mannered species (3/10), while Tire Track Eel is moderately assertive (6/10). This modest difference means Tire Track Eel may occasionally assert dominance over Bala Shark.

Bala Shark 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, Bala Shark 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 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bala Shark 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.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Smooth Gravel (Sensitive Barbels), Sand (Sifters), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

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

Frequently Asked Questions

Can Bala Shark and Tire Track Eel live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 816 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Bala Shark 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 Bala Shark and Tire Track Eel together?

Keep the aquarium between 22°C and 28°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Bala Shark or Tire Track Eel aggressive?

Bala Shark is generally mild-mannered (3/10) and Tire Track Eel is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Bala Shark and Tire Track Eel need?

Both species overlap in the 6.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

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.
