Can Motoro Stingray and Reedfish (Ropefish) Live Together?

Possible with Caution

Keeping Motoro Stingray and Reedfish (Ropefish) together is possible but requires caution due to mismatched flow preferences. Provide a spacious tank of at least 750 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Motoro Stingray 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

Motoro Stingray is a moderately assertive species (5/10), while Reedfish (Ropefish) is generally mild-mannered (3/10). This modest difference means Motoro Stingray may occasionally assert dominance over Reedfish (Ropefish).

Motoro Stingray and Reedfish (Ropefish) 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 5–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Motoro Stingray and Reedfish (Ropefish) together, plan for an aquarium of at least 750 litres with a minimum length of 180 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.

Motoro Stingray 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.

Frequently Asked Questions

Can Motoro Stingray and Reedfish (Ropefish) live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 750 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Motoro Stingray and Reedfish (Ropefish) need?

A minimum of 750 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 Motoro Stingray and Reedfish (Ropefish) 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 Motoro Stingray or Reedfish (Ropefish) aggressive?

Motoro Stingray is moderately assertive (5/10) and Reedfish (Ropefish) is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Motoro Stingray 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.

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.
