Reviewed by Guidarium Editorial DeskUpdated May 3, 2026
Not Recommended

Trout Cichlid (Champsochromis) and Uaru 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 Trout Cichlid (Champsochromis) and Uaru?

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

Trout Cichlid (Champsochromis) is a semi-aggressive species (7/10), while Uaru is generally mild-mannered (4/10). This modest difference means Trout Cichlid (Champsochromis) may occasionally assert dominance over Uaru.

Trout Cichlid (Champsochromis) and Uaru 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Trout Cichlid (Champsochromis) is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 27°C and 28°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.

The pH requirements of Trout Cichlid (Champsochromis) (7.8–8.6) and Uaru (5–7) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Trout Cichlid (Champsochromis) needs 10–25 dGH while Uaru requires 1–8 dGH.

Tank Setup

To house Trout Cichlid (Champsochromis) and Uaru together, plan for an aquarium of at least 500 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). 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

Trout Cichlid (Champsochromis) and Uaru 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 Trout Cichlid (Champsochromis) and Uaru.

Frequently Asked Questions

Can Trout Cichlid (Champsochromis) and Uaru live together?

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

What size tank do Trout Cichlid (Champsochromis) and Uaru need?

A minimum of 500 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 Trout Cichlid (Champsochromis) and Uaru together?

Keep the aquarium between 27°C and 28°C. A target of around 27.5°C sits comfortably within both species' preferred ranges.

Are Trout Cichlid (Champsochromis) or Uaru aggressive?

Trout Cichlid (Champsochromis) is semi-aggressive (7/10) and Uaru is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Trout Cichlid (Champsochromis) and Uaru need?

Their pH requirements do not overlap. Trout Cichlid (Champsochromis) prefers 7.8–8.6, while Uaru needs 5–7. This makes them incompatible in the same water chemistry.

How do I manage Trout Cichlid (Champsochromis)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Trout Cichlid (Champsochromis) 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.
