Can Amano Shrimp and Bucktooth Tetra (Exodon) Live Together?
Amano Shrimp and Bucktooth Tetra (Exodon) 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.
At a Glance
Behaviour & Temperament
Amano Shrimp is a peaceful species (1/10), while Bucktooth Tetra (Exodon) is highly aggressive (9/10). This notable difference means Bucktooth Tetra (Exodon) may occasionally assert dominance over Amano Shrimp.
Large aggression gap (8 points) between Amano Shrimp and Bucktooth Tetra (Exodon) increases stress risk for the more peaceful fish.
Amano Shrimp and Bucktooth Tetra (Exodon) 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.
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 23°C and 28°C. Aim for the midpoint of this range (around 25.5°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 4–14 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Amano Shrimp and Bucktooth Tetra (Exodon) together, plan for an aquarium of at least 240 litres with a minimum length of 120 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, Driftwood (Digestion/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 Bucktooth Tetra (Exodon) 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 Bucktooth Tetra (Exodon) need?▾
A minimum of 240 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 Bucktooth Tetra (Exodon) together?▾
Keep the aquarium between 23°C and 28°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are Amano Shrimp or Bucktooth Tetra (Exodon) aggressive?▾
Amano Shrimp is peaceful (1/10) and Bucktooth Tetra (Exodon) is highly aggressive (9/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Amano Shrimp and Bucktooth Tetra (Exodon) 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 Bucktooth Tetra (Exodon) nip Amano Shrimp's fins?▾
Bucktooth Tetra (Exodon) is a known fin nipper. If Amano Shrimp has long or flowing fins, there is a real risk of fin damage. Keeping Bucktooth Tetra (Exodon) in a larger group can help redirect nipping behaviour toward conspecifics.
