Can Aequidens sp. Atabapo and White Cheeked Goby Live Together?

Aequidens sp. Atabapo is a moderately assertive species (6/10), while White Cheeked Goby is generally mild-mannered (4/10). This modest difference means Aequidens sp. Atabapo may occasionally assert dominance over White Cheeked Goby.

Aequidens sp. Atabapo and White Cheeked Goby 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.

There is no temperature overlap between Aequidens sp. Atabapo (25–29°C) and White Cheeked Goby (15–24°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6.5 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–8 dGH. Regular testing will ensure conditions stay within this range.

To house Aequidens sp. Atabapo and White Cheeked Goby together, plan for an aquarium of at least 110 litres with a minimum length of 90 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), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Aequidens sp. Atabapo prefers Low (Still Water) flow while White Cheeked Goby needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Aequidens sp. Atabapo and White Cheeked Goby 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. Aequidens sp. Atabapo is a known shrimp eater and may prey on small invertebrates or nano fish like White Cheeked Goby.
