Can your tank handle False Glass Catfish and Trout Cichlid (Champsochromis)?

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

False Glass Catfish is a peaceful species (2/10), while Trout Cichlid (Champsochromis) is semi-aggressive (7/10). This notable difference means Trout Cichlid (Champsochromis) may occasionally assert dominance over False Glass Catfish.

False Glass Catfish and Trout Cichlid (Champsochromis) 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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

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

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

Tank Setup

To house False Glass Catfish and Trout Cichlid (Champsochromis) 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: Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Sand (Sifters). 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

False Glass Catfish and Trout Cichlid (Champsochromis) 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 False Glass Catfish and Trout Cichlid (Champsochromis).

Frequently Asked Questions

Can False Glass Catfish and Trout Cichlid (Champsochromis) live together?

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

What size tank do False Glass Catfish and Trout Cichlid (Champsochromis) 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 False Glass Catfish and Trout Cichlid (Champsochromis) together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are False Glass Catfish or Trout Cichlid (Champsochromis) aggressive?

False Glass Catfish is peaceful (2/10) and Trout Cichlid (Champsochromis) is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do False Glass Catfish and Trout Cichlid (Champsochromis) need?

Their pH requirements do not overlap. False Glass Catfish prefers 5–7, while Trout Cichlid (Champsochromis) needs 7.8–8.6. 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.
