Avoid
Venustus Cichlid and Bronze Corydoras compatibility verdict
Short answer: No, this pairing should usually be avoided. Plan for at least 125 gallons before adjusting for group size, filtration, and aquascape layout.
aggression_riskAggression or territorial behavior needs extra space, cover, and careful observation.
bioload_warningAdult size and waste production require large-tank filtration and maintenance planning.
predator_prey_riskVenustus is a large predatory Lake Malawi cichlid; small community fish, dwarf shrimp, and small bottom fish are prey-sized or biotope mismatches.

This verdict assumes normal social groups, not one stressed specimen. Bronze Corydoras should be planned at 6+ before judging long-term compatibility.
Real-World Experience
Textbook score vs observed behavior
A compatibility score checks adult size, temperature, pH, hardness, temperament, and tank volume. Real tanks add variables the score cannot see directly: feeding aggression, cave ownership, plant cover, and whether fish can constantly see each other.
Line-of-sight and swim-zone pressure
Venustus Cichlid and Bronze Corydoras use different swim zones, but feeding time and open sightlines can still change behavior. Start with at least 125 gallons, then use hardscape, tall plants, and separated feeding zones to reduce chasing before it becomes a pattern.

Troubleshooting aggression between Venustus Cichlid and Bronze Corydoras
Problems can happen even when the gallon number is technically adequate. Check feeding order, repeated access to the same cave or plant mass, school size, and whether the aquascape gives either fish a direct line of sight across the whole tank.
Bottom dweller competition between Venustus Cichlid and Bronze Corydoras
If either species uses the lower half of the tank, add more broken sightlines and avoid placing all food in one corner. Bottom pressure is more about usable floor space than total water volume.
How to break line-of-sight to reduce aggression
Use tall plants, rock piles, driftwood, and separate feeding stations so a dominant fish cannot patrol one open lane from end to end.
