Can Ghost Shrimp and Reedfish (Ropefish) Live Together?

Reviewed by Guidarium Editorial DeskUpdated April 28, 2026
Not Recommended

Ghost Shrimp and Reedfish (Ropefish) are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Ghost Shrimp 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

Ghost Shrimp is a peaceful species (1/10), while Reedfish (Ropefish) is generally mild-mannered (3/10). This modest difference means Reedfish (Ropefish) may occasionally assert dominance over Ghost Shrimp.

Ghost Shrimp 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.

There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

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 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 Ghost Shrimp and Reedfish (Ropefish) together, plan for an aquarium of at least 180 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.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Plants - Densely covered, Leaf Litter/Blackwater, Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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 Usually Fails in Practice

Ghost Shrimp and Reedfish (Ropefish) are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Diet & Feeding

Feeding time deserves special attention with this pairing. Reedfish (Ropefish) is a known shrimp eater and may prey on small invertebrates or nano fish like Ghost Shrimp.

Frequently Asked Questions

Can Ghost Shrimp and Reedfish (Ropefish) live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Ghost Shrimp and Reedfish (Ropefish) need?

A minimum of 180 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 Ghost Shrimp 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 Ghost Shrimp or Reedfish (Ropefish) aggressive?

Ghost Shrimp is peaceful (1/10) and Reedfish (Ropefish) is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Ghost Shrimp and Reedfish (Ropefish) 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 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.
