Both fish can tolerate a pH between 6.5 and 7.8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 5–20 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Denison Barb (Roseline Shark) and White Cloud Mountain Minnow together, plan for an aquarium of at least 240 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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, Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Denison Barb (Roseline Shark) is a plant destroyer, which conflicts with White Cloud Mountain Minnow's requirement for live plants. Compromise where possible or prioritise the more critical need.
Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.
