Can African Pipefish and Betta Macrostoma Live Together?
Keeping African Pipefish and Betta Macrostoma together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 80 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Can your tank handle African Pipefish 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
African Pipefish 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 African Pipefish.
Large aggression gap (6 points) between African Pipefish and Betta Macrostoma increases stress risk for the more peaceful fish.
African Pipefish 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: Betta Macrostoma is a known jumper, so a tight-fitting lid is essential.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both African Pipefish and Betta Macrostoma to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.
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.
Both fish can tolerate a pH between 6 and 6. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 4–5 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house African Pipefish 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.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Plants - Densely covered, Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Floating. 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 African Pipefish and Betta Macrostoma live together?
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 80 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do African Pipefish 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 African Pipefish and Betta Macrostoma 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 African Pipefish or Betta Macrostoma aggressive?
African Pipefish 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 African Pipefish and Betta Macrostoma need?
Both species overlap in the 6–6 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
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.
