Provide a spacious tank of at least 816 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Bronze Corydoras is a peaceful species (1/10), while Indonesian Datnoid (Tiger Fish) is moderately assertive (6/10). This notable difference means Indonesian Datnoid (Tiger Fish) may occasionally assert dominance over Bronze Corydoras.
Bronze Corydoras and Indonesian Datnoid (Tiger Fish) 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.
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 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 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 5–15 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Bronze Corydoras and Indonesian Datnoid (Tiger Fish) together, plan for an aquarium of at least 816 litres with a minimum length of 180 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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: Sand (Sifters), Driftwood (Digestion/Hiding), Plants - Densely covered. 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.
