Can Apistogramma borellii (Umbrella Cichlid) and Bumblebee Goby (Brackish) Live Together?

Apistogramma borellii (Umbrella Cichlid) is a generally mild-mannered species (3/10), while Bumblebee Goby (Brackish) is generally mild-mannered (4/10). This modest difference means Bumblebee Goby (Brackish) may occasionally assert dominance over Apistogramma borellii (Umbrella Cichlid).

Apistogramma borellii (Umbrella Cichlid) and Bumblebee Goby (Brackish) both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks. Shrimp eaters may also prey on very small nano fish.

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 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 10–10 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 Apistogramma borellii (Umbrella Cichlid) and Bumblebee Goby (Brackish) together, plan for an aquarium of at least 55 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), Leaf Litter/Blackwater, Plants - Densely covered, Driftwood (Digestion/Hiding), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels). 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.

Apistogramma borellii (Umbrella Cichlid) and Bumblebee Goby (Brackish) 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.

Feeding time deserves special attention with this pairing. Apistogramma borellii (Umbrella Cichlid) is a known shrimp eater and may prey on small invertebrates or nano fish like Bumblebee Goby (Brackish).
