Can New Guinea Tigerfish and Tiger Shrimp Live Together?
New Guinea Tigerfish and Tiger Shrimp are not recommended as tank mates due to incompatible hardness ranges and 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.
At a Glance
Can your tank handle New Guinea Tigerfish and Tiger Shrimp?
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
New Guinea Tigerfish is a semi-aggressive species (7/10), while Tiger Shrimp is peaceful (0/10). This notable difference means New Guinea Tigerfish may occasionally assert dominance over Tiger Shrimp.
Large aggression gap (7 points) between New Guinea Tigerfish and Tiger Shrimp increases stress risk for the more peaceful fish.
New Guinea Tigerfish and Tiger Shrimp 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.
There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..
Water Parameters
The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.
Both fish can tolerate a pH between 7 and 7.4. Maintaining a stable value within this band is more important than hitting an exact number.
Hardness requirements are incompatible: New Guinea Tigerfish needs 10–25 dGH while Tiger Shrimp requires 4–8 dGH.
Tank Setup
To house New Guinea Tigerfish and Tiger Shrimp together, plan for an aquarium of at least 600 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.
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: Driftwood (Digestion/Hiding), Sand (Sifters), Established Algae (Otocinclus), Plants - Densely covered, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
Why This Pairing Usually Fails in Practice
New Guinea Tigerfish and Tiger Shrimp 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.
Suitable Tank Sizes
Standard aquarium sizes large enough for both New Guinea Tigerfish and Tiger Shrimp.
Frequently Asked Questions
Can New Guinea Tigerfish and Tiger Shrimp live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do New Guinea Tigerfish and Tiger Shrimp need?
A minimum of 600 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 New Guinea Tigerfish and Tiger Shrimp together?
Keep the aquarium between 24°C and 25°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.
Are New Guinea Tigerfish or Tiger Shrimp aggressive?
New Guinea Tigerfish is semi-aggressive (7/10) and Tiger Shrimp is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do New Guinea Tigerfish and Tiger Shrimp need?
Both species overlap in the 7–7.4 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage New Guinea Tigerfish's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives New Guinea Tigerfish space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
