Behaviour & Temperament
Bumblebee Catfish (South American) is a generally mild-mannered species (3/10), while Sterba's Corydoras is peaceful (1/10). This modest difference means Bumblebee Catfish (South American) may occasionally assert dominance over Sterba's Corydoras.
Bumblebee Catfish (South American) and Sterba's Corydoras 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion.
Worth noting: Bumblebee Catfish (South American) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.
Water Parameters
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 6 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 4–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Bumblebee Catfish (South American) and Sterba's Corydoras 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.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Leaf Litter/Blackwater, Sand (Sifters). 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.

What pH do Bumblebee Catfish (South American) and Sterba's Corydoras need?
Both species overlap in the 6–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Does Bumblebee Catfish (South American) being nocturnal affect compatibility?
Bumblebee Catfish (South American) is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Bumblebee Catfish (South American) during evening hours.
