Can Amano Shrimp and Shell Dweller (Multi) Live Together?
Amano Shrimp and Shell Dweller (Multi) are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Behaviour & Temperament
Amano Shrimp is a peaceful species (1/10), while Shell Dweller (Multi) is moderately assertive (6/10). This notable difference means Shell Dweller (Multi) may occasionally assert dominance over Amano Shrimp.
Amano Shrimp and Shell Dweller (Multi) 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: 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 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.
The pH requirements of Amano Shrimp (6–7.5) and Shell Dweller (Multi) (7.8–9) 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 Shell Dweller (Multi) together, plan for an aquarium of at least 46 litres with a minimum length of 45 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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), Shells (Breeding/Hiding). 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.
Frequently Asked Questions
Can Amano Shrimp and Shell Dweller (Multi) 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 Shell Dweller (Multi) need?▾
A minimum of 46 litres (tank length at least 45 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 Shell Dweller (Multi) together?▾
Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are Amano Shrimp or Shell Dweller (Multi) aggressive?▾
Amano Shrimp is peaceful (1/10) and Shell Dweller (Multi) 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 Shell Dweller (Multi) need?▾
Their pH requirements do not overlap. Amano Shrimp prefers 6–7.5, while Shell Dweller (Multi) needs 7.8–9. This makes them incompatible in the same water chemistry.
How do I manage Shell Dweller (Multi)'s territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Shell Dweller (Multi) 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.
