Can Goby Pleco (Pitbull Pleco) and Green Neon Tetra Live Together?

Goby Pleco (Pitbull Pleco) is a peaceful species (1/10), while Green Neon Tetra is peaceful (0/10). This modest difference means Goby Pleco (Pitbull Pleco) may occasionally assert dominance over Green Neon Tetra.

In terms of spatial distribution, Goby Pleco (Pitbull Pleco) prefers the Bottom (Substrate) zone, whereas Green Neon Tetra occupies the Middle (Open Water) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

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

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 6 and 6.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–8 dGH. Regular testing will ensure conditions stay within this range.

To house Goby Pleco (Pitbull Pleco) and Green Neon Tetra together, plan for an aquarium of at least 60 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), Driftwood (Digestion/Hiding), Established Algae (Otocinclus), Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating. Meeting these requirements will help both species thrive.

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