Can Red Zebra Cichlid live with Ember Tetra?

AvoidRed Zebra Cichlid and Ember Tetra 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.

Predation risk: will Red Zebra Cichlid eat Ember Tetra?
Yes, this is a major risk. Adult Red Zebra Cichlid reach about 5", while Ember Tetra stay near 0.8". That size gap can turn Ember Tetra 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. Red Zebra Cichlid should be planned at 4+; Ember Tetra should be planned at 8+ 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
Red Zebra Cichlid and Ember Tetra 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.

Confidence: high. Aggression, predator/prey, shrimp risk, schooling, and tank size rules are evaluated from curated freshwater attributes.
Troubleshooting aggression between Red Zebra Cichlid and Ember Tetra
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 Red Zebra Cichlid and Ember Tetra
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.
