Can White Cloud Mountain Minnow and Zebra Shovelnose (Tigrinus Catfish) Live Together?

White Cloud Mountain Minnow is a peaceful species (1/10), while Zebra Shovelnose (Tigrinus Catfish) is generally mild-mannered (4/10). This modest difference means Zebra Shovelnose (Tigrinus Catfish) may occasionally assert dominance over White Cloud Mountain Minnow.

In terms of spatial distribution, White Cloud Mountain Minnow prefers the Top (Surface) and Middle (Open Water) zones, whereas Zebra Shovelnose (Tigrinus Catfish) 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.

There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Worth noting: White Cloud Mountain Minnow is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between White Cloud Mountain Minnow (14–22°C) and Zebra Shovelnose (Tigrinus Catfish) (24–28°C). This fundamental mismatch makes long-term cohabitation impractical.

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 5–12 dGH. Regular testing will ensure conditions stay within this range.

To house White Cloud Mountain Minnow 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: Plants - Densely covered, Smooth Gravel (Sensitive Barbels), Sand (Sifters), 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.

White Cloud Mountain Minnow 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.
