Compatibility brief

Can Corydoras Catfish live with Green Terror?

VerdictRISKY

Risky. This mix is commonly discouraged for typical setups.

Corydoras Catfish + Green Terror: Aggression mismatch. Green Terror is aggressive, while Corydoras Catfish is peaceful. The aggressive fish will likely bully or harm the peaceful one. 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.
