Can Debauwi Catfish (Three-Striped Glass Catfish) and Three-striped Dwarf Cichlid Live Together?

Debauwi Catfish (Three-Striped Glass Catfish) is a peaceful species (2/10), while Three-striped Dwarf Cichlid is generally mild-mannered (4/10). This modest difference means Three-striped Dwarf Cichlid may occasionally assert dominance over Debauwi Catfish (Three-Striped Glass Catfish).

Debauwi Catfish (Three-Striped Glass Catfish) and Three-striped Dwarf 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.

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.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Debauwi Catfish (Three-Striped Glass Catfish) and Three-striped Dwarf Cichlid to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

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. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–10 dGH. Regular testing will ensure conditions stay within this range.

To house Debauwi Catfish (Three-Striped Glass Catfish) and Three-striped Dwarf Cichlid 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.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Plants - Densely covered, Sand (Sifters), Leaf Litter/Blackwater. 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Debauwi Catfish (Three-Striped Glass Catfish) and Three-striped Dwarf Cichlid need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Feeding time deserves special attention with this pairing. Debauwi Catfish (Three-Striped Glass Catfish) is an aggressive eater that may prevent Three-striped Dwarf Cichlid 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 Three-striped Dwarf Cichlid receives an adequate share.
