Compatibility brief
Can African Cichlid live with Oscar?
Caution. Check the issues below before buying.
African Cichlid + Oscar: Narrow pH overlap. These fish can share water but their ideal pH ranges overlap only slightly. Aim to keep pH stable in the shared range. Outcomes still depend on your tank shape, maintenance routine, and individual fish.
Compatibility score
Profile confidence: low
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
300L
Combined minimum footprint reference for these two species: about 300L (larger active fish often want more length).
Oscar (35cm adult) may treat small African Cichlid (~15cm) as food once grown — plan adult sizes, not shop sizes.

Plan further
Try both species in the full-stock tank check, or open either fish profile for mates lists. 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): Based on typical aquarium care sources; trade names can be ambiguous, so details may vary between setups.
