Can Bumblebee Goby (Brackish) and Celebes Rainbowfish Live Together?

Bumblebee Goby (Brackish) is a generally mild-mannered species (4/10), while Celebes Rainbowfish is peaceful (2/10). This modest difference means Bumblebee Goby (Brackish) may occasionally assert dominance over Celebes Rainbowfish.

In terms of spatial distribution, Bumblebee Goby (Brackish) prefers the Bottom (Substrate) zone, whereas Celebes Rainbowfish occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Celebes Rainbowfish is a known jumper, so a tight-fitting lid is essential.

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 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 10–25 dGH. Regular testing will ensure conditions stay within this range.

To house Bumblebee Goby (Brackish) and Celebes Rainbowfish together, plan for an aquarium of at least 75 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.

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: Sand (Sifters), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels), Plants - lighly 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.
