Can Debauwi Catfish (Three-Striped Glass Catfish) and Hi Fin Peppered Cory Live Together?

Both Debauwi Catfish (Three-Striped Glass Catfish) and Hi Fin Peppered Cory are peaceful species with an aggression score of 2/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

In terms of spatial distribution, Debauwi Catfish (Three-Striped Glass Catfish) prefers the Middle (Open Water) and Top (Surface) zones, whereas Hi Fin Peppered Cory 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: Hi Fin Peppered Cory is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Debauwi Catfish (Three-Striped Glass Catfish) is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between Debauwi Catfish (Three-Striped Glass Catfish) (24–28°C) and Hi Fin Peppered Cory (16–23°C). This fundamental mismatch makes long-term cohabitation impractical.

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 Hi Fin Peppered Cory 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), Smooth Gravel (Sensitive Barbels). 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 Hi Fin Peppered Cory 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.
