VerdictGOOD

Often a workable match in a suitable, well-run tank. Still verify behaviour in your setup.

Classic community staple pairing. One honest caveat: 'Corydoras' in shops spans many species with different temperature bands — confirm which cory you are buying, then this pairing is as safe as community fishkeeping gets.

  4. Data or identification limits

    Top issue

    At least one fish has common trade or ID ambiguity, so the numbers here may not match the individual in the shop.

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: high. Checked against several solid care sources that mostly agree. At least one species here has common trade-name ambiguity.

What tank size do you need for Corydoras Catfish and Zebra Danio together?
Plan around 60 litres as the working minimum. That figure comes from each species' published minimum and their group needs, and it assumes adult sizes, not shop sizes.
What's the main risk?
Data or identification limits. That is the first thing to plan around. The matching entry under assessment details on this page explains the reasoning and the numbers behind it.
What should you check before buying?
Corydoras Catfish should be kept in a group of at least 6 for best health and behaviour. Zebra Danio should be kept in a group of at least 6 for best health and behaviour.
