Can Altolamprologus Compressiceps and Debauwi Catfish (Three-Striped Glass Catfish) Live Together?

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

Altolamprologus Compressiceps and Debauwi Catfish (Three-Striped Glass Catfish) 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. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

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 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 Debauwi Catfish (Three-Striped Glass Catfish) (6–7.5) 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 Altolamprologus Compressiceps and Debauwi Catfish (Three-Striped Glass Catfish) 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), 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.

Altolamprologus Compressiceps and Debauwi Catfish (Three-Striped Glass Catfish) 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.

Feeding time deserves special attention with this pairing. Debauwi Catfish (Three-Striped Glass Catfish) is an aggressive eater that may prevent Altolamprologus Compressiceps from getting enough food.

Because Debauwi Catfish (Three-Striped Glass Catfish) is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Altolamprologus Compressiceps receives an adequate share.
