Can False Siamese Algae Eater (Stonelapping Minnow) and Xenotilapia ochrogenys Live Together?

False Siamese Algae Eater (Stonelapping Minnow) is a moderately assertive species (5/10), while Xenotilapia ochrogenys is generally mild-mannered (4/10). This modest difference means False Siamese Algae Eater (Stonelapping Minnow) may occasionally assert dominance over Xenotilapia ochrogenys.

False Siamese Algae Eater (Stonelapping Minnow) and Xenotilapia ochrogenys 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: False Siamese Algae Eater (Stonelapping Minnow) is a known jumper, so a tight-fitting lid is essential.

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 False Siamese Algae Eater (Stonelapping Minnow) (6–7.5) and Xenotilapia ochrogenys (8–9) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

To house False Siamese Algae Eater (Stonelapping Minnow) and Xenotilapia ochrogenys together, plan for an aquarium of at least 268 litres with a minimum length of 120 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: Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Sand (Sifters). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

False Siamese Algae Eater (Stonelapping Minnow) and Xenotilapia ochrogenys 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.
