Behaviour & Temperament

Dwarf Pea Puffer is a semi-aggressive species (8/10), while Indonesian Datnoid (Tiger Fish) is moderately assertive (6/10). This modest difference means Dwarf Pea Puffer may occasionally assert dominance over Indonesian Datnoid (Tiger Fish).

Dwarf Pea Puffer and Indonesian Datnoid (Tiger Fish) 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 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: Shrimp eaters may also prey on very small nano fish.

Water Parameters

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Dwarf Pea Puffer and Indonesian Datnoid (Tiger Fish) together, plan for an aquarium of at least 816 litres with a minimum length of 180 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: Plants - Densely covered, Sand (Sifters), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

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

Frequently Asked Questions

Can Dwarf Pea Puffer and Indonesian Datnoid (Tiger Fish) live together?

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

What size tank do Dwarf Pea Puffer and Indonesian Datnoid (Tiger Fish) need?

A minimum of 816 litres (tank length at least 180 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 Dwarf Pea Puffer and Indonesian Datnoid (Tiger Fish) together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Dwarf Pea Puffer or Indonesian Datnoid (Tiger Fish) aggressive?

Dwarf Pea Puffer is semi-aggressive (8/10) and Indonesian Datnoid (Tiger Fish) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Dwarf Pea Puffer and Indonesian Datnoid (Tiger Fish) need?

Both species overlap in the 6.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Dwarf Pea Puffer nip Indonesian Datnoid (Tiger Fish)'s fins?

Dwarf Pea Puffer is a known fin nipper. If Indonesian Datnoid (Tiger Fish) has long or flowing fins, there is a real risk of fin damage. Keeping Dwarf Pea Puffer in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Dwarf Pea Puffer's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Dwarf Pea Puffer 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.
