Can Mbu Puffer and Scarlet Badis Live Together?

🔴Not Recommended

Mbu Puffer and Scarlet Badis are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament

Mbu Puffer is a semi-aggressive species (7/10), while Scarlet Badis is generally mild-mannered (3/10). This notable difference means Mbu Puffer may occasionally assert dominance over Scarlet Badis.

Mbu Puffer and Scarlet Badis 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Water Parameters

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 10–20 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Mbu Puffer and Scarlet Badis together, plan for an aquarium of at least 1800 litres with a minimum length of 240 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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: Sand (Sifters), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Plants - lighly covered. Meeting these requirements will help both species thrive.

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

Diet & Feeding

Feeding time deserves special attention with this pairing. Mbu Puffer is an aggressive eater that may prevent Scarlet Badis from getting enough food.

Because Mbu Puffer is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Scarlet Badis receives an adequate share.

Frequently Asked Questions

Can Mbu Puffer and Scarlet Badis live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Mbu Puffer and Scarlet Badis need?

A minimum of 1800 litres (tank length at least 240 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 Mbu Puffer and Scarlet Badis together?

Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Mbu Puffer or Scarlet Badis aggressive?

Mbu Puffer is semi-aggressive (7/10) and Scarlet Badis is generally mild-mannered (3/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Mbu Puffer and Scarlet Badis need?

Both species overlap in the 7–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Mbu Puffer nip Scarlet Badis's fins?

Mbu Puffer is a known fin nipper. If Scarlet Badis has long or flowing fins, there is a real risk of fin damage. Keeping Mbu Puffer in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Scarlet Badis's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Scarlet Badis 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.
