Venustus Cichlid and Blue Acara 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.
biotope_mismatchVenustus needs a large hard-water Malawi predator setup and should not be planned as a mixed community or New World cichlid tankmate.

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 Blue Acara may compete for the same swimming lane, food path, or line-of-sight territory. 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 Blue Acara
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 Blue Acara
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.
