Can Chuco Cichlid and False Glass Catfish Live Together?

Chuco Cichlid is a semi-aggressive species (7/10), while False Glass Catfish is peaceful (2/10). This notable difference means Chuco Cichlid may occasionally assert dominance over False Glass Catfish.

Chuco Cichlid and False Glass Catfish both frequent the Middle (Open Water) 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: Aggressive fish may bully and stress shy, slow-moving species.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

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

Hardness requirements are incompatible: Chuco Cichlid needs 10–20 dGH while False Glass Catfish requires 1–8 dGH.

To house Chuco Cichlid and False Glass Catfish together, plan for an aquarium of at least 450 litres with a minimum length of 120 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), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Chuco Cichlid is a plant destroyer, which conflicts with False Glass Catfish's requirement for live plants. Compromise where possible or prioritise the more critical need.

Chuco Cichlid prefers High (River/Stream) flow while False Glass Catfish needs Low (Still Water) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Chuco Cichlid and False Glass Catfish 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.
