Can Betta Macrostoma and Red Zebra Cichlid (Cherry Red) Live Together?

Betta Macrostoma is a moderately assertive species (6/10), while Red Zebra Cichlid (Cherry Red) is semi-aggressive (8/10). This modest difference means Red Zebra Cichlid (Cherry Red) may occasionally assert dominance over Betta Macrostoma.

Betta Macrostoma and Red Zebra Cichlid (Cherry Red) both frequent the Middle (Open Water) and 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.

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species. Two territorial species may clash over territory, especially in smaller tanks.

Worth noting: Betta Macrostoma is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

The pH requirements of Betta Macrostoma (4–6) and Red Zebra Cichlid (Cherry Red) (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Betta Macrostoma needs 0–5 dGH while Red Zebra Cichlid (Cherry Red) requires 10–25 dGH.

To house Betta Macrostoma and Red Zebra Cichlid (Cherry Red) together, plan for an aquarium of at least 292 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: Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Floating, Sand (Sifters), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Betta Macrostoma and Red Zebra Cichlid (Cherry Red) 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.
