Can Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk Live Together?
Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.
Behaviour & Temperament
Debauwi Catfish (Three-Striped Glass Catfish) is a peaceful species (2/10), while Red Fin Caudopunk is moderately assertive (6/10). This notable difference means Red Fin Caudopunk may occasionally assert dominance over Debauwi Catfish (Three-Striped Glass Catfish).
Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk 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.
Water Parameters
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 Debauwi Catfish (Three-Striped Glass Catfish) (6–7.5) and Red Fin Caudopunk (8–9) 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.
Tank Setup
To house Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk 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), Shells (Breeding/Hiding). 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.
Why This Pairing Usually Fails in Practice
Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk 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.

Frequently Asked Questions
Can Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk need?
A minimum of 110 litres (tank length at least 90 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk together?
Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are Debauwi Catfish (Three-Striped Glass Catfish) or Red Fin Caudopunk aggressive?
Debauwi Catfish (Three-Striped Glass Catfish) is peaceful (2/10) and Red Fin Caudopunk is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Debauwi Catfish (Three-Striped Glass Catfish) and Red Fin Caudopunk need?
Their pH requirements do not overlap. Debauwi Catfish (Three-Striped Glass Catfish) prefers 6–7.5, while Red Fin Caudopunk needs 8–9. This makes them incompatible in the same water chemistry.
How do I manage Red Fin Caudopunk's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Red Fin Caudopunk space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
