Can Loxozonus Corydoras (C079/C082) and Red Eye Tetra Live Together?

Loxozonus Corydoras (C079/C082) is a peaceful species (0/10), while Red Eye Tetra is generally mild-mannered (3/10). This modest difference means Red Eye Tetra may occasionally assert dominance over Loxozonus Corydoras (C079/C082).

In terms of spatial distribution, Loxozonus Corydoras (C079/C082) prefers the Bottom (Substrate) zone, whereas Red Eye Tetra occupies the Middle (Open Water) and Top (Surface) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

To improve the chances of a peaceful coexistence in this community tank: Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

The safe temperature window for both species falls between 22°C and 26°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7.2. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 3–12 dGH. Regular testing will ensure conditions stay within this range.

To house Loxozonus Corydoras (C079/C082) and Red Eye Tetra 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: Sand (Sifters), Leaf Litter/Blackwater, Plants - Densely covered. Meeting these requirements will help both species thrive.

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

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Loxozonus Corydoras (C079/C082) and Red Eye Tetra need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.
