Can Betta Macrostoma and Blood Parrot Cichlid Live Together?
Betta Macrostoma and Blood Parrot Cichlid are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Betta Macrostoma and Blood Parrot Cichlid?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament
Both Betta Macrostoma and Blood Parrot Cichlid are moderately assertive species with an aggression score of 6/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Betta Macrostoma and Blood Parrot Cichlid 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion. 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.
Water Parameters
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 Blood Parrot Cichlid (6.5–8) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Betta Macrostoma needs 0–5 dGH while Blood Parrot Cichlid requires 8–20 dGH.

Tank Setup
To house Betta Macrostoma and Blood Parrot Cichlid together, plan for an aquarium of at least 200 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), Smooth Gravel (Sensitive Barbels). 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.

Frequently Asked Questions
Can Betta Macrostoma and Blood Parrot Cichlid live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Betta Macrostoma and Blood Parrot Cichlid need?
A minimum of 200 litres (tank length at least 120 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Betta Macrostoma and Blood Parrot Cichlid together?
Keep the aquarium between 24°C and 25°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.
Are Betta Macrostoma or Blood Parrot Cichlid aggressive?
Betta Macrostoma is moderately assertive (6/10) and Blood Parrot Cichlid is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Betta Macrostoma and Blood Parrot Cichlid need?
Their pH requirements do not overlap. Betta Macrostoma prefers 4–6, while Blood Parrot Cichlid needs 6.5–8. This makes them incompatible in the same water chemistry.
How do I manage Betta Macrostoma's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Betta Macrostoma space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
