Can Bamboo Shrimp and Betta Macrostoma Live Together?
Bamboo Shrimp and Betta Macrostoma 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 Bamboo Shrimp and Betta Macrostoma?
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
Bamboo Shrimp is a peaceful species (0/10), while Betta Macrostoma is moderately assertive (6/10). This notable difference means Betta Macrostoma may occasionally assert dominance over Bamboo Shrimp.
Large aggression gap (6 points) between Bamboo Shrimp and Betta Macrostoma increases stress risk for the more peaceful fish.
Bamboo Shrimp and Betta Macrostoma 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.
Worth noting: Bamboo Shrimp is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 22°C and 25°C. Aim for the midpoint of this range (around 23.5°C) for optimal comfort.
The pH requirements of Bamboo Shrimp (6.5–7.5) and Betta Macrostoma (4–6) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Bamboo Shrimp needs 6–15 dGH while Betta Macrostoma requires 0–5 dGH.
Tank Setup
To house Bamboo Shrimp and Betta Macrostoma together, plan for an aquarium of at least 80 litres with a minimum length of 60 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: Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Plants - Floating. Meeting these requirements will help both species thrive.
Bamboo Shrimp prefers High (River/Stream) flow while Betta Macrostoma needs Low (Still Water) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
Why This Pairing Usually Fails in Practice
Bamboo Shrimp and Betta Macrostoma 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.

Frequently Asked Questions
Can Bamboo Shrimp and Betta Macrostoma live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Bamboo Shrimp and Betta Macrostoma need?
A minimum of 80 litres (tank length at least 60 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 Bamboo Shrimp and Betta Macrostoma together?
Keep the aquarium between 22°C and 25°C. A target of around 23.5°C sits comfortably within both species' preferred ranges.
Are Bamboo Shrimp or Betta Macrostoma aggressive?
Bamboo Shrimp is peaceful (0/10) and Betta Macrostoma is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Bamboo Shrimp and Betta Macrostoma need?
Their pH requirements do not overlap. Bamboo Shrimp prefers 6.5–7.5, while Betta Macrostoma needs 4–6. 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.
