Tiger Barb vs Pygmy Corydoras: can they live together?

A structured comparison of water overlap, adult size, social needs and behavioral risk.

good

Generally compatible on core signals

No major temperature, pH, size or behavioural conflict is flagged by the planning model.

Practical response: Still observe individual behaviour and verify species-specific care before purchase.

Behavior and space

Fast, assertive schooling fish; larger groups help, but long-finned tankmates remain a poor choice. Tiny social corys that use both lower and mid water and look best in larger groups.

A compatibility answer should also consider the actual tank dimensions, number of each fish, filtration, planting and other occupants. Two species can be reasonable together in a long, structured aquarium yet become a poor pairing when compressed into a small footprint.

Common questions

Can Tiger Barb live with Pygmy Corydoras?

The StockingLab verdict is good: No major temperature, pH, size or behavioural conflict is flagged by the planning model.

Do their temperatures overlap?

22–26°C / 71.6–78.8°F shared range.

Should I trust compatibility calculators completely?

No. Individual behavior, sex ratios, breeding condition, aquascape and tank size can change the outcome. Use the result to identify risks, then verify care requirements before purchase.
