Can Bronze Corydoras Live With Guppy?
Yes, bronze corydoras and guppies coexist well in 20 gallons or larger with overlapping temperatures of 72-79°F and pH of 7.0-7.8.
Why
- Temperature overlap spans 72-79°F, comfortable for both corydoras and guppies.
- Corydoras are bottom-dwelling sand sifters and guppies are top-level swimmers, so they use completely different tank zones.
- pH overlap of 7.0-7.8 is within acceptable range for both species.
- Both are peaceful community species that thrive in groups, making them natural tankmates.
What could go wrong
Guppies breed prolifically and if fry survive in the gravel, corydoras will eat them. This is not harmful, but it means you will not be raising guppy fry in this setup.
