Can Amano Shrimp and Malawi Gar Live Together?
Amano Shrimp and Malawi Gar are not recommended as tank mates due to conflicting pH requirements 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 Amano Shrimp and Malawi Gar?
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
Amano Shrimp is a peaceful species (1/10), while Malawi Gar is moderately assertive (6/10). This notable difference means Malawi Gar may occasionally assert dominance over Amano Shrimp.
Amano Shrimp and Malawi Gar both frequent the Bottom (Substrate) and Middle (Open Water) 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..
Worth noting: Amano Shrimp 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.
The pH requirements of Amano Shrimp (6–7.5) and Malawi Gar (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–14 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Amano Shrimp and Malawi Gar together, plan for an aquarium of at least 350 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: Established Algae (Otocinclus), Plants - Densely covered, Sand (Sifters), 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
Amano Shrimp and Malawi Gar 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 Amano Shrimp and Malawi Gar.
125 Gallon Standard
150 Gallon High
180 Gallon Standard
350 Liter (120cm Deep)
450 Liter (150cm Standard)
Frequently Asked Questions
Can Amano Shrimp and Malawi Gar live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Amano Shrimp and Malawi Gar need?
A minimum of 350 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 Amano Shrimp and Malawi Gar 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 Amano Shrimp or Malawi Gar aggressive?
Amano Shrimp is peaceful (1/10) and Malawi Gar is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Amano Shrimp and Malawi Gar need?
Their pH requirements do not overlap. Amano Shrimp prefers 6–7.5, while Malawi Gar needs 7.8–8.6. This makes them incompatible in the same water chemistry.
How do I manage Malawi Gar's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Malawi Gar 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.
