Can Amano Shrimp and Paradise Fish Live Together?
Keeping Amano Shrimp and Paradise Fish together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 90 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Amano Shrimp is a peaceful species (1/10), while Paradise Fish is semi-aggressive (8/10). This notable difference means Paradise Fish may occasionally assert dominance over Amano Shrimp.
Large aggression gap (7 points) between Amano Shrimp and Paradise Fish increases stress risk for the more peaceful fish.
Amano Shrimp and Paradise Fish both frequent the 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.
Worth noting: Amano Shrimp is a known jumper, so a tight-fitting lid is essential.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Amano Shrimp and Paradise Fish to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.
Water Parameters
The safe temperature window for both species falls between 18°C and 26°C. Aim for the midpoint of this range (around 22.0°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 5–14 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Amano Shrimp and Paradise Fish together, plan for an aquarium of at least 90 litres with a minimum length of 80 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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: Established Algae (Otocinclus), Plants - Densely covered, Plants - Floating. 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 Paradise Fish live together?▾
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 90 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Amano Shrimp and Paradise Fish need?▾
A minimum of 90 litres (tank length at least 80 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 Paradise Fish together?▾
Keep the aquarium between 18°C and 26°C. A target of around 22.0°C sits comfortably within both species' preferred ranges.
Are Amano Shrimp or Paradise Fish aggressive?▾
Amano Shrimp is peaceful (1/10) and Paradise Fish is semi-aggressive (8/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Amano Shrimp and Paradise Fish 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.
Will Paradise Fish nip Amano Shrimp's fins?▾
Paradise Fish is a known fin nipper. If Amano Shrimp has long or flowing fins, there is a real risk of fin damage. Keeping Paradise Fish in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Paradise Fish's territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Paradise Fish 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.
