Can Blood Parrot Cichlid and Loxozonus Corydoras (C079/C082) Live Together?

Blood Parrot Cichlid is a moderately assertive species (6/10), while Loxozonus Corydoras (C079/C082) is peaceful (0/10). This notable difference means Blood Parrot Cichlid may occasionally assert dominance over Loxozonus Corydoras (C079/C082).

Large aggression gap (6 points) between Blood Parrot Cichlid and Loxozonus Corydoras (C079/C082) increases stress risk for the more peaceful fish.

Blood Parrot Cichlid and Loxozonus Corydoras (C079/C082) 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.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Blood Parrot Cichlid and Loxozonus Corydoras (C079/C082) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

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.

Both fish can tolerate a pH between 6.5 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 8–12 dGH. Regular testing will ensure conditions stay within this range.

To house Blood Parrot Cichlid and Loxozonus Corydoras (C079/C082) 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.

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), Smooth Gravel (Sensitive Barbels), Leaf Litter/Blackwater. 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Blood Parrot Cichlid and Loxozonus Corydoras (C079/C082) 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.
