Behaviour & Temperament
Abei Puffer is a highly aggressive species (9/10), while Goldie River Rainbowfish is peaceful (2/10). This notable difference means Abei Puffer may occasionally assert dominance over Goldie River Rainbowfish.
Large aggression gap (7 points) between Abei Puffer and Goldie River Rainbowfish increases stress risk for the more peaceful fish.
Abei Puffer and Goldie River Rainbowfish both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Worth noting: Goldie River Rainbowfish is a known jumper, so a tight-fitting lid is essential.
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 Abei Puffer and Goldie River Rainbowfish 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.
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 7 and 7.8. 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.

Tank Setup
To house Abei Puffer and Goldie River Rainbowfish together, plan for an aquarium of at least 130 litres with a minimum length of 90 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: Sand (Sifters), Driftwood (Digestion/Hiding), Plants - Densely covered. 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.

What water temperature is best for Abei Puffer and Goldie River Rainbowfish 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 Abei Puffer or Goldie River Rainbowfish aggressive?
Abei Puffer is highly aggressive (9/10) and Goldie River Rainbowfish is peaceful (2/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Abei Puffer and Goldie River Rainbowfish need?
Both species overlap in the 7–7.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Abei Puffer nip Goldie River Rainbowfish's fins?
Abei Puffer is a known fin nipper. If Goldie River Rainbowfish has long or flowing fins, there is a real risk of fin damage. Keeping Abei Puffer in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Abei Puffer's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Abei 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.
