## Habitat

Corydoras are generally found in a variety of freshwater environments, such as rivers, streams, and tributaries. They are native to slow-moving and almost still (but seldom stagnant) streams and small rivers of South America, where the water is shallow and very murky.

## Aquarium use

Corydoras are popular and hardy aquarium fish. They are well-known for their vibrant colors and unique patterns. They are also famous for their peaceful behavior. The Corydoras is a wonderful fish to many home aquariums.

### In the wild

_Corydoras_ in the wild feed on small aquatic invertebrates, like worms, crustaceans, and insect larvae.

### Aquarium

_Corydoras_ in an aquarium will eat live food like brine shrimp and others.
