Can Zebra Shovelnose (Tigrinus Catfish) and Zebra Spiny Eel Live Together?

Zebra Shovelnose (Tigrinus Catfish) is a generally mild-mannered species (4/10), while Zebra Spiny Eel is peaceful (2/10). This modest difference means Zebra Shovelnose (Tigrinus Catfish) may occasionally assert dominance over Zebra Spiny Eel.

Zebra Shovelnose (Tigrinus Catfish) and Zebra Spiny 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Zebra Spiny Eel is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Zebra Shovelnose (Tigrinus Catfish) is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.8 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 5–12 dGH. Regular testing will ensure conditions stay within this range.

To house Zebra Shovelnose (Tigrinus Catfish) and Zebra Spiny Eel together, plan for an aquarium of at least 1135 litres with a minimum length of 240 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Plants - Densely covered. 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Zebra Shovelnose (Tigrinus Catfish) and Zebra Spiny Eel need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.
