Can Aequidens sp. Atabapo and Banded Chromide Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 1, 2026
Not Recommended

Aequidens sp. Atabapo and Banded Chromide 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.

Can your tank handle Aequidens sp. Atabapo and Banded Chromide?

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

Aequidens sp. Atabapo is a moderately assertive species (6/10), while Banded Chromide is moderately assertive (5/10). This modest difference means Aequidens sp. Atabapo may occasionally assert dominance over Banded Chromide.

Aequidens sp. Atabapo and Banded Chromide 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 29°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.

The pH requirements of Aequidens sp. Atabapo (4.5–7) and Banded Chromide (7.5–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Aequidens sp. Atabapo needs 1–8 dGH while Banded Chromide requires 10–25 dGH.

Tank Setup

To house Aequidens sp. Atabapo and Banded Chromide together, plan for an aquarium of at least 450 litres with a minimum length of 150 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, Smooth Gravel (Sensitive Barbels). 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.

Why This Pairing Usually Fails in Practice

Aequidens sp. Atabapo and Banded Chromide 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 Aequidens sp. Atabapo and Banded Chromide.

Frequently Asked Questions

Can Aequidens sp. Atabapo and Banded Chromide 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 Banded Chromide need?

A minimum of 450 litres (tank length at least 150 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 Banded Chromide together?

Keep the aquarium between 25°C and 29°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.

Are Aequidens sp. Atabapo or Banded Chromide aggressive?

Aequidens sp. Atabapo is moderately assertive (6/10) and Banded Chromide is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Aequidens sp. Atabapo and Banded Chromide need?

Their pH requirements do not overlap. Aequidens sp. Atabapo prefers 4.5–7, while Banded Chromide needs 7.5–8.5. 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.
