Can Fahaka Puffer and Golden Wonder Killifish Live Together?
Keeping Fahaka Puffer and Golden Wonder Killifish together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 540 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Fahaka Puffer is a highly aggressive species (10/10), while Golden Wonder Killifish is moderately assertive (6/10). This notable difference means Fahaka Puffer may occasionally assert dominance over Golden Wonder Killifish.
In terms of spatial distribution, Fahaka Puffer prefers the Middle (Open Water) and Bottom (Substrate) zones, whereas Golden Wonder Killifish occupies the Top (Surface) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
Worth noting: Golden Wonder Killifish 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 Fahaka Puffer and Golden Wonder Killifish 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.
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 6.8 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 Fahaka Puffer and Golden Wonder Killifish together, plan for an aquarium of at least 540 litres with a minimum length of 150 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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), Shells (Breeding/Hiding), Plants - Floating. Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

What pH do Fahaka Puffer and Golden Wonder Killifish need?▾
Both species overlap in the 6.8–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Fahaka Puffer's territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Fahaka 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.
