Possible with Caution

Keeping Reedfish (Ropefish) and Tiger Shovelnose Catfish together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 3800 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Reedfish (Ropefish) and Tiger Shovelnose Catfish?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Reedfish (Ropefish) is a generally mild-mannered species (3/10), while Tiger Shovelnose Catfish is moderately assertive (6/10). This modest difference means Tiger Shovelnose Catfish may occasionally assert dominance over Reedfish (Ropefish).

Reedfish (Ropefish) and Tiger Shovelnose Catfish 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: Reedfish (Ropefish) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Reedfish (Ropefish) is a known jumper, so a tight-fitting lid is essential.

Water Parameters

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.

Both fish can tolerate a pH between 6 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 Reedfish (Ropefish) and Tiger Shovelnose Catfish together, plan for an aquarium of at least 3800 litres with a minimum length of 300 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 low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Needs Extra Planning in Practice

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Reedfish (Ropefish) and Tiger Shovelnose Catfish 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.

Frequently Asked Questions

Can Reedfish (Ropefish) and Tiger Shovelnose Catfish live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 3800 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Reedfish (Ropefish) and Tiger Shovelnose Catfish need?

A minimum of 3800 litres (tank length at least 300 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 Reedfish (Ropefish) and Tiger Shovelnose Catfish together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Reedfish (Ropefish) or Tiger Shovelnose Catfish aggressive?

Reedfish (Ropefish) is generally mild-mannered (3/10) and Tiger Shovelnose Catfish is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Reedfish (Ropefish) and Tiger Shovelnose Catfish need?

Both species overlap in the 6–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Does Reedfish (Ropefish) being nocturnal affect compatibility?

Reedfish (Ropefish) 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 Reedfish (Ropefish) during evening hours.
