Can Banded Leporinus and Reedfish (Ropefish) Live Together?

Possible with Caution

Keeping Banded Leporinus and Reedfish (Ropefish) together is possible but requires caution due to differing aggression levels and mismatched flow preferences. Provide a spacious tank of at least 380 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Banded Leporinus and Reedfish (Ropefish)?

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

Banded Leporinus is a semi-aggressive species (7/10), while Reedfish (Ropefish) is generally mild-mannered (3/10). This notable difference means Banded Leporinus may occasionally assert dominance over Reedfish (Ropefish).

Banded Leporinus and Reedfish (Ropefish) both frequent the Middle (Open Water) and 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, Banded Leporinus 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. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

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 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 Banded Leporinus and Reedfish (Ropefish) together, plan for an aquarium of at least 380 litres with a minimum length of 120 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: Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Sand (Sifters), Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Banded Leporinus is a plant destroyer, which conflicts with Reedfish (Ropefish)'s requirement for live plants. Compromise where possible or prioritise the more critical need.

Banded Leporinus prefers High (River/Stream) flow while Reedfish (Ropefish) needs Low (Still Water) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Banded Leporinus and Reedfish (Ropefish).

Frequently Asked Questions

Can Banded Leporinus and Reedfish (Ropefish) live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 380 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Banded Leporinus and Reedfish (Ropefish) need?

A minimum of 380 litres (tank length at least 120 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 Banded Leporinus and Reedfish (Ropefish) 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 Banded Leporinus or Reedfish (Ropefish) aggressive?

Banded Leporinus is semi-aggressive (7/10) and Reedfish (Ropefish) is generally mild-mannered (3/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Banded Leporinus and Reedfish (Ropefish) 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.

Will Banded Leporinus nip Reedfish (Ropefish)'s fins?

Banded Leporinus is a known fin nipper. If Reedfish (Ropefish) has long or flowing fins, there is a real risk of fin damage. Keeping Banded Leporinus in a larger group can help redirect nipping behaviour toward conspecifics.

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.
