Can Leopard Bushfish (Ctenopoma) and Neon Blue Goby Live Together?

Leopard Bushfish (Ctenopoma) is a generally mild-mannered species (4/10), while Neon Blue Goby is generally mild-mannered (3/10). This modest difference means Leopard Bushfish (Ctenopoma) may occasionally assert dominance over Neon Blue Goby.

Leopard Bushfish (Ctenopoma) and Neon Blue 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

Worth noting: Leopard Bushfish (Ctenopoma) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 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 5–12 dGH. Regular testing will ensure conditions stay within this range.

To house Leopard Bushfish (Ctenopoma) and Neon Blue 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: Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels), Sand (Sifters). Meeting these requirements will help both species thrive.

Leopard Bushfish (Ctenopoma) prefers Low (Still Water) flow while Neon Blue Goby needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Leopard Bushfish (Ctenopoma) and Neon Blue 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. Leopard Bushfish (Ctenopoma) is a known shrimp eater and may prey on small invertebrates or nano fish like Neon Blue Goby.
