Can Siamese Algae Eater and White Cloud Mountain Minnow Live Together?

Siamese Algae Eater is a generally mild-mannered species (3/10), while White Cloud Mountain Minnow is peaceful (1/10). This modest difference means Siamese Algae Eater may occasionally assert dominance over White Cloud Mountain Minnow.

Siamese Algae Eater and White Cloud Mountain Minnow 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: Siamese Algae Eater is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 22°C and 22°C. Aim for the midpoint of this range (around 22.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 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 5–15 dGH. Regular testing will ensure conditions stay within this range.

To house Siamese Algae Eater and White Cloud Mountain Minnow together, plan for an aquarium of at least 132 litres with a minimum length of 90 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: Established Algae (Otocinclus), Driftwood (Digestion/Hiding), Plants - lighly covered, Plants - Densely covered, 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.
