Can Bee Shrimp and Dwarf Pea Puffer Live Together?

Bee Shrimp is a peaceful species (0/10), while Dwarf Pea Puffer is semi-aggressive (8/10). This notable difference means Dwarf Pea Puffer may occasionally assert dominance over Bee Shrimp.

Large aggression gap (8 points) between Bee Shrimp and Dwarf Pea Puffer increases stress risk for the more peaceful fish.

Bee Shrimp and Dwarf Pea 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.

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

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 Bee Shrimp and Dwarf Pea Puffer 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. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

The safe temperature window for both species falls between 22°C and 24°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 6.8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–6 dGH. Regular testing will ensure conditions stay within this range.

To house Bee Shrimp and Dwarf Pea Puffer together, plan for an aquarium of at least 112 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: Soil / Nutrient Rich, Leaf Litter/Blackwater, Plants - Densely covered, Sand (Sifters). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Bee Shrimp requires Soil / Nutrient Rich, while Dwarf Pea Puffer 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Bee Shrimp and Dwarf Pea Puffer need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Feeding time deserves special attention with this pairing. Dwarf Pea Puffer is a known shrimp eater and may prey on small invertebrates or nano fish like Bee Shrimp.
