AvoidMaingano Cichlid and Fancy Goldfish compatibility verdict
Short answer: No, this pairing should usually be avoided. Plan for at least 55 gallons before adjusting for group size, filtration, and aquascape layout.

Schooling and group-size requirements
This verdict assumes normal social groups, not one stressed specimen. Maingano Cichlid should be planned at 4+; Fancy Goldfish should be planned at 2+ 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
Maingano Cichlid and Fancy Goldfish use different swim zones, but feeding time and open sightlines can still change behavior. Start with at least 55 gallons, then use hardscape, tall plants, and separated feeding zones to reduce chasing before it becomes a pattern.

Troubleshooting aggression between Maingano Cichlid and Fancy Goldfish
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 Maingano Cichlid and Fancy Goldfish
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.
