Reviewed by Guidarium Editorial DeskUpdated May 2, 2026
Not Recommended

Altolamprologus Compressiceps and Apistogramma Orange-tail 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 Altolamprologus Compressiceps and Apistogramma Orange-tail?

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

Altolamprologus Compressiceps is a moderately assertive species (6/10), while Apistogramma Orange-tail is moderately assertive (5/10). This modest difference means Altolamprologus Compressiceps may occasionally assert dominance over Apistogramma Orange-tail.

Altolamprologus Compressiceps and Apistogramma Orange-tail both frequent the Bottom (Substrate) and 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.

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 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Altolamprologus Compressiceps (7.8–9) and Apistogramma Orange-tail (5.5–7.2) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Altolamprologus Compressiceps needs 10–25 dGH while Apistogramma Orange-tail requires 1–8 dGH.

Tank Setup

To house Altolamprologus Compressiceps and Apistogramma Orange-tail together, plan for an aquarium of at least 150 litres with a minimum length of 90 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), Shells (Breeding/Hiding), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered. 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.

Why This Pairing Usually Fails in Practice

Altolamprologus Compressiceps and Apistogramma Orange-tail 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.

Frequently Asked Questions

Can Altolamprologus Compressiceps and Apistogramma Orange-tail live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Altolamprologus Compressiceps and Apistogramma Orange-tail need?

A minimum of 150 litres (tank length at least 90 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 Altolamprologus Compressiceps and Apistogramma Orange-tail 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 Altolamprologus Compressiceps or Apistogramma Orange-tail aggressive?

Altolamprologus Compressiceps is moderately assertive (6/10) and Apistogramma Orange-tail is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Altolamprologus Compressiceps and Apistogramma Orange-tail need?

Their pH requirements do not overlap. Altolamprologus Compressiceps prefers 7.8–9, while Apistogramma Orange-tail needs 5.5–7.2. This makes them incompatible in the same water chemistry.

How do I manage Altolamprologus Compressiceps's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Altolamprologus Compressiceps 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.
