Avoid
Auratus Cichlid and Pea Puffer 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.
predator_prey_riskPea Puffer is prey-sized compared with adult Auratus Cichlid.
aggression_riskAggression or territorial behavior needs extra space, cover, and careful observation.
biotope_mismatchMalawi mbuna need hard alkaline Lake Malawi-style housing and should not be mixed with New World cichlids, goldfish, puffers, or general community fish.

Predation risk: will Auratus Cichlid eat Pea Puffer?
Yes, this is a major risk. Adult Auratus Cichlid reach about 4.5", while Pea Puffer stay near 1". That size gap can turn Pea Puffer into prey, especially at night, during feeding, or once the larger fish is fully grown.
Schooling and group-size requirements
This verdict assumes normal social groups, not one stressed specimen. Auratus Cichlid should be planned at 4+ 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
Auratus Cichlid and Pea Puffer may compete for the same swimming lane, food path, or line-of-sight territory. Start with at least 55 gallons, then use hardscape, tall plants, and separated feeding zones to reduce chasing before it becomes a pattern.

Confidence: high. Aggression, predator/prey, shrimp risk, schooling, and tank size rules are evaluated from curated freshwater attributes.
Troubleshooting aggression between Auratus Cichlid and Pea Puffer
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 Auratus Cichlid and Pea Puffer
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.
