Can Bumblebee Goby (Brackish) and Long-Finned African Tetra Live Together?

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

In terms of spatial distribution, Bumblebee Goby (Brackish) prefers the Bottom (Substrate) zone, whereas Long-Finned African Tetra 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: Long-Finned African Tetra is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 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 10–19 dGH. Regular testing will ensure conditions stay within this range.

Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.

To house Bumblebee Goby (Brackish) and Long-Finned African Tetra together, plan for an aquarium of at least 200 litres with a minimum length of 120 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), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Bumblebee Goby (Brackish) prefers Low (Still Water) flow while Long-Finned African Tetra needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Bumblebee Goby (Brackish) and Long-Finned African Tetra are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
