Compatibility brief

Can Corydoras Catfish live with Discus?

VerdictRISKY

Risky. This mix is commonly discouraged for typical setups.

Corydoras Catfish + Discus: Incompatible temperature requirements. Corydoras Catfish needs 20–26°C and Discus needs 28–32°C. Their ranges do not overlap. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.

Concrete changes, not "research more" filler.

  • Corydoras Catfish should be kept in a group of at least 6 for best health and behaviour.
  • Discus should be kept in a group of at least 4 for best health and behaviour.
  • These fish cannot be comfortably housed together. Their temperature needs are incompatible.

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.
