Compatibility brief
Can Checkerboard cichlid live with Corydoras Catfish?
Risky. This mix is commonly discouraged for typical setups.
Checkerboard cichlid + Corydoras Catfish: Incompatible pH requirements. Checkerboard cichlid prefers pH 3.5–5.5 and Corydoras Catfish prefers pH 6–7.5. Their ranges do not overlap. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.

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: high. Based on multiple reputable aquarium care sources with strong agreement.
