Can Bee Shrimp and Green Spotted Puffer (Brackish) Live Together?

Bee Shrimp is a peaceful species (0/10), while Green Spotted Puffer (Brackish) is highly aggressive (9/10). This notable difference means Green Spotted Puffer (Brackish) may occasionally assert dominance over Bee Shrimp.

Large aggression gap (9 points) between Bee Shrimp and Green Spotted Puffer (Brackish) increases stress risk for the more peaceful fish.

Bee Shrimp and Green Spotted Puffer (Brackish) 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.

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species. Shrimp eaters may also prey on very small nano fish.

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 Green Spotted Puffer (Brackish) (7.5–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Bee Shrimp needs 3–6 dGH while Green Spotted Puffer (Brackish) requires 12–30 dGH.

Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.

To house Bee Shrimp and Green Spotted Puffer (Brackish) together, plan for an aquarium of at least 114 litres with a minimum length of 80 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). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Bee Shrimp requires Soil / Nutrient Rich, while Green Spotted Puffer (Brackish) requires Sand (Sifters). 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 Green Spotted Puffer (Brackish) 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. Green Spotted Puffer (Brackish) is a known shrimp eater and may prey on small invertebrates or nano fish like Bee Shrimp.
