Can Bumblebee Cichlid and Pygmy Corydoras Live Together?

Bumblebee Cichlid is a semi-aggressive species (8/10), while Pygmy Corydoras is peaceful (0/10). This notable difference means Bumblebee Cichlid may occasionally assert dominance over Pygmy Corydoras.

Large aggression gap (8 points) between Bumblebee Cichlid and Pygmy Corydoras increases stress risk for the more peaceful fish.

Bumblebee Cichlid and Pygmy Corydoras both frequent the Middle (Open Water) and 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion.

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.

The pH requirements of Bumblebee Cichlid (7.8–8.6) and Pygmy Corydoras (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

To house Bumblebee Cichlid and Pygmy Corydoras together, plan for an aquarium of at least 200 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. Meeting these requirements will help both species thrive.

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

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

Bumblebee Cichlid and Pygmy Corydoras 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.
