Can Bronze Corydoras and Forktail Blue-eye Live Together?
Yes, Bronze Corydoras and Forktail Blue-eye are ideal tank mates. Both species share compatible water parameters and peaceful temperaments, making them well-suited for a community aquarium. They occupy different areas of the water column, which reduces competition for space. A minimum tank size of 72 litres is recommended.
At a Glance
Behaviour & Temperament
Bronze Corydoras is a peaceful species (1/10), while Forktail Blue-eye is peaceful (2/10). This modest difference means Forktail Blue-eye may occasionally assert dominance over Bronze Corydoras.
In terms of spatial distribution, Bronze Corydoras prefers the Bottom (Substrate) zone, whereas Forktail Blue-eye occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
Worth noting: Forktail Blue-eye is a known jumper, so a tight-fitting lid is essential.
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 7 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 Forktail Blue-eye together, plan for an aquarium of at least 72 litres with a minimum length of 60 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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), 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.
