Can Bee Shrimp and Mbu Puffer Live Together?

Bee Shrimp is a peaceful species (0/10), while Mbu Puffer is semi-aggressive (7/10). This notable difference means Mbu Puffer may occasionally assert dominance over Bee Shrimp.

Large aggression gap (7 points) between Bee Shrimp and Mbu Puffer increases stress risk for the more peaceful fish.

Bee Shrimp and Mbu Puffer both frequent the 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 Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) 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.

The safe temperature window for both species falls between 24°C and 24°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

The pH requirements of Bee Shrimp (5.5–6.8) and Mbu Puffer (7–8) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Bee Shrimp needs 3–6 dGH while Mbu Puffer requires 10–25 dGH.

To house Bee Shrimp and Mbu Puffer together, plan for an aquarium of at least 1500 litres with a minimum length of 240 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: Soil / Nutrient Rich, Leaf Litter/Blackwater, Plants - Densely covered, Sand (Sifters), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Bee Shrimp requires Soil / Nutrient Rich, while Mbu Puffer requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Bee Shrimp requires Soil / Nutrient Rich, while Mbu Puffer requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Compromise where possible or prioritise the more critical need.

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

Bee Shrimp and Mbu Puffer 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.

Feeding time deserves special attention with this pairing. Mbu Puffer is an aggressive eater that may prevent Bee Shrimp 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 Bee Shrimp receives an adequate share.
