Can Leopard Frog Pleco (L134) and Spotfin Goby Cichlid Live Together?

Leopard Frog Pleco (L134) is a generally mild-mannered species (3/10), while Spotfin Goby Cichlid is moderately assertive (6/10). This modest difference means Spotfin Goby Cichlid may occasionally assert dominance over Leopard Frog Pleco (L134).

Leopard Frog Pleco (L134) and Spotfin Goby Cichlid 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.

Worth noting: Leopard Frog Pleco (L134) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 26°C and 27°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

The pH requirements of Leopard Frog Pleco (L134) (6–7.4) and Spotfin Goby Cichlid (8–9) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

To house Leopard Frog Pleco (L134) and Spotfin Goby Cichlid together, plan for an aquarium of at least 75 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: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Sand (Sifters). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Leopard Frog Pleco (L134) and Spotfin Goby Cichlid 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.
