Can Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish) Live Together?
Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish) 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 Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish)?
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
Red Fin Caudopunk is a moderately assertive species (6/10), while Zebra Shovelnose (Tigrinus Catfish) is generally mild-mannered (4/10). This modest difference means Red Fin Caudopunk may occasionally assert dominance over Zebra Shovelnose (Tigrinus Catfish).
Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish) both frequent the Bottom (Substrate) 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: Zebra Shovelnose (Tigrinus 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 Red Fin Caudopunk (8–9) and Zebra Shovelnose (Tigrinus Catfish) (6.5–7.5) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish) together, plan for an aquarium of at least 1135 litres with a minimum length of 240 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/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
Red Fin Caudopunk and Zebra Shovelnose (Tigrinus 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.
Frequently Asked Questions
Can Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish) need?
A minimum of 1135 litres (tank length at least 240 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 Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish) 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 Red Fin Caudopunk or Zebra Shovelnose (Tigrinus Catfish) aggressive?
Red Fin Caudopunk is moderately assertive (6/10) and Zebra Shovelnose (Tigrinus Catfish) is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Red Fin Caudopunk and Zebra Shovelnose (Tigrinus Catfish) need?
Their pH requirements do not overlap. Red Fin Caudopunk prefers 8–9, while Zebra Shovelnose (Tigrinus Catfish) needs 6.5–7.5. 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.
