Can Debauwi Catfish (Three-Striped Glass Catfish) and Yellow Peacock Cichlid Live Together?

Debauwi Catfish (Three-Striped Glass Catfish) is a peaceful species (2/10), while Yellow Peacock Cichlid is moderately assertive (6/10). This notable difference means Yellow Peacock Cichlid may occasionally assert dominance over Debauwi Catfish (Three-Striped Glass Catfish).

Debauwi Catfish (Three-Striped Glass Catfish) and Yellow Peacock Cichlid 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.

Worth noting: Debauwi Catfish (Three-Striped Glass Catfish) is a known jumper, so a tight-fitting lid is essential.

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 Debauwi Catfish (Three-Striped Glass Catfish) (6–7.5) and Yellow Peacock Cichlid (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

To house Debauwi Catfish (Three-Striped Glass Catfish) and Yellow Peacock Cichlid together, plan for an aquarium of at least 200 litres with a minimum length of 120 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: Driftwood (Digestion/Hiding), Plants - Densely covered, Sand (Sifters). 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.

Debauwi Catfish (Three-Striped Glass Catfish) and Yellow Peacock Cichlid 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.
