Compatibility brief
Can African Cichlid live with X-ray tetra?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: low
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
200L
Combined minimum footprint reference for these two species: about 200L (larger active fish often want more length).
African Cichlid (15cm adult) may treat small X-ray tetra (~4.5cm) as food once grown — plan adult sizes, not shop sizes.
African Cichlid (aggressive) and X-ray tetra (peaceful) are far apart on aggression — bullying or injury is a common outcome in average community layouts.
Assessment details
Aggression mismatch
Top issueAfrican Cichlid is aggressive, while X-ray tetra is peaceful. The aggressive fish will likely bully or harm the peaceful one.
Compatible temperature range
Both fish can comfortably share similar water temperatures.
Incompatible pH requirements
African Cichlid prefers pH 7.8–9 and X-ray tetra prefers pH 5.5–7.5. Their ranges do not overlap.
Hardness preference mismatch
African Cichlid prefers hard water and X-ray tetra prefers soft water. One of them lives outside its comfort band long-term — pick the tank's water for the more sensitive species.

- •African Cichlid should be kept in a group of at least 6 for best health and behaviour.
- •X-ray tetra should be kept in a group of at least 6 for best health and behaviour.

Plan further
Check each species’ mates list, size the glass, then verify the full stock in the builder. Methodology explains how verdicts are produced.
Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.
Profile data confidence: medium. Driven by the lower-confidence profile (African Cichlid): Typical care sources — trade names for this fish get mixed up, so verify the ID before you buy.
