Can Bumblebee Goby (Brackish) and Norman's Lampeye Killifish Live Together?

Bumblebee Goby (Brackish) is a generally mild-mannered species (4/10), while Norman's Lampeye Killifish is peaceful (1/10). This modest difference means Bumblebee Goby (Brackish) may occasionally assert dominance over Norman's Lampeye Killifish.

In terms of spatial distribution, Bumblebee Goby (Brackish) prefers the Bottom (Substrate) zone, whereas Norman's Lampeye Killifish 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.

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

Worth noting: Norman's Lampeye Killifish 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 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 10–15 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. An aquarium test kit is recommended for monitoring.

To house Bumblebee Goby (Brackish) and Norman's Lampeye Killifish together, plan for an aquarium of at least 46 litres with a minimum length of 45 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: Sand (Sifters), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Plants - Floating. 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.

Feeding time deserves special attention with this pairing. Bumblebee Goby (Brackish) is a known shrimp eater and may prey on small invertebrates or nano fish like Norman's Lampeye Killifish.
