Can pygmy corydoras and fancy goldfish live together?
With care
Pygmy corydoras and fancy goldfish can share a tank, but there is something to watch.
Why
- Their temperature ranges only meet at 72°F (22°C), which leaves no margin.
- An adult fancy goldfish is big enough to eat pygmy corydoras.

The smallest tank for both
A 29 gallons (110 L) tank holds 6 pygmy corydoras and 1 fancy goldfish at about 62% of its stocking limit, which leaves room for more.
