Can Dwarf Pea Puffer and Nyererei Victorian Cichlid Live Together?

Dwarf Pea Puffer is a semi-aggressive species (8/10), while Nyererei Victorian Cichlid is semi-aggressive (7/10). This modest difference means Dwarf Pea Puffer may occasionally assert dominance over Nyererei Victorian Cichlid.

Both Dwarf Pea Puffer and Nyererei Victorian Cichlid are highly aggressive, increasing the risk of violent confrontations.

Dwarf Pea Puffer and Nyererei Victorian Cichlid 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.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks. 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 Dwarf Pea Puffer and Nyererei Victorian Cichlid to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. 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 23°C and 27°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.4 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 8–15 dGH. Regular testing will ensure conditions stay within this range.

To house Dwarf Pea Puffer and Nyererei Victorian Cichlid together, plan for an aquarium of at least 342 litres with a minimum length of 100 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, Sand (Sifters). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Nyererei Victorian Cichlid is a plant destroyer, which conflicts with Dwarf Pea Puffer's requirement for live plants. 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. Dwarf Pea Puffer and Nyererei Victorian Cichlid 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. Nyererei Victorian Cichlid is a known shrimp eater and may prey on small invertebrates or nano fish like Dwarf Pea Puffer.
