Can Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish) Live Together?
Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish) are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament
Aequidens sp. Atabapo is a moderately assertive species (6/10), while Silver Tiger Perch (American Tigerfish) is semi-aggressive (7/10). This modest difference means Silver Tiger Perch (American Tigerfish) may occasionally assert dominance over Aequidens sp. Atabapo.
Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish) 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.
Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.
Water Parameters
The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.
The pH requirements of Aequidens sp. Atabapo (4.5–7) and Silver Tiger Perch (American Tigerfish) (7.5–9) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Aequidens sp. Atabapo needs 1–8 dGH while Silver Tiger Perch (American Tigerfish) requires 15–30 dGH.

Tank Setup
To house Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish) together, plan for an aquarium of at least 650 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: Sand (Sifters), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish).

Frequently Asked Questions
Can Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish) need?
A minimum of 650 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 Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish) together?
Keep the aquarium between 25°C and 28°C. A target of around 26.5°C sits comfortably within both species' preferred ranges.
Are Aequidens sp. Atabapo or Silver Tiger Perch (American Tigerfish) aggressive?
Aequidens sp. Atabapo is moderately assertive (6/10) and Silver Tiger Perch (American Tigerfish) is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Aequidens sp. Atabapo and Silver Tiger Perch (American Tigerfish) need?
Their pH requirements do not overlap. Aequidens sp. Atabapo prefers 4.5–7, while Silver Tiger Perch (American Tigerfish) needs 7.5–9. This makes them incompatible in the same water chemistry.
How do I manage Aequidens sp. Atabapo's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Aequidens sp. Atabapo 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.
