Can Debauwi Catfish (Three-Striped Glass Catfish) and Sterba's Corydoras Live Together?

Debauwi Catfish (Three-Striped Glass Catfish) is a peaceful species (2/10), while Sterba's Corydoras is peaceful (1/10). This modest difference means Debauwi Catfish (Three-Striped Glass Catfish) may occasionally assert dominance over Sterba's Corydoras.

In terms of spatial distribution, Debauwi Catfish (Three-Striped Glass Catfish) prefers the Middle (Open Water) and Top (Surface) zones, whereas Sterba's Corydoras occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

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.

Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range.

To house Debauwi Catfish (Three-Striped Glass Catfish) and Sterba's Corydoras together, plan for an aquarium of at least 110 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: 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 Sterba's Corydoras work best when the tank gives each fish enough room to use its preferred level of the aquarium and enough cover to avoid constant visual contact. The score matters, but the real-world success usually comes from matching their pace, keeping water stable, and resisting the urge to crowd the tank just because the pair looks safe on paper.
