The Corydoras family of Catfish is super common in the wild and in the Aquarium hobby. They come in a wide variety of colors and sizes too, from the tiny pygmy corydoras to much larger species. You’ll commonly see green or albino ones at big box stores, if you go to a good LFS (Local Fish Store) you’ll find the more interesting spotted, striped and other unique Corydoras species. They sift the gravel/sand for food so don’t use huge gravel as substrate if keeping Cory Catfish.

Some species of Corydoras have been successfully bred in home aquariums. I have personally had eggs laid by Corydoras Aeneus but they were not fertilized. This was done in both 20 and 29 gallon aquariums with no special care. The tanks were both fine gravel/sand bottoms and had live plants along with some Mopani driftwood to lower the PH.
If you do choose to add some to your tank get as many as possible. They are a shoaling species, preferring to be in groups. I would say a group of 5-6 or more is best, it also increases your chances of breeding if you are interested in breeding Corydoras Catfish.
