Behaviour & Temperament
Bristlenose Pleco is a peaceful species (2/10), while Zebra Shovelnose (Tigrinus Catfish) is generally mild-mannered (4/10). This modest difference means Zebra Shovelnose (Tigrinus Catfish) may occasionally assert dominance over Bristlenose Pleco.
Bristlenose Pleco 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: Bristlenose Pleco is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, 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.
Both fish can tolerate a pH between 6.5 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 4–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Bristlenose Pleco 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: Driftwood (Digestion/Hiding), Established Algae (Otocinclus), 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.
