When combining species in your aquarium, it’s vital to check the compatibility of the species you are considering adding to your tank to make sure they can peacefully coexist.
Cory catfish (also known as corydoras) are not usually compatible with cichlids, especially African cichlids. Most cichlids are aggressive or semi-aggressive in nature, and will readily attack the small, docile corydoras.
Read on to learn which species are suitable tank mates for cichlids and corydoras.
About Cory Catfish
These friendly, low-maintenance fish originate are fun to watch and clean detritus from your tank, contributing to a healthier aquarium community. They are curious and peaceful fish that differ from other catfish species due to their plates of bone-like material along their sides, which categorizes them as “armored catfish.”
Cory catfish range from 1 – 2.5 inches in length and thrive in any size aquariums. They are popular additions to freshwater aquariums and are ideal for beginner fish owners because of their ease of care.
Corydoras will easily share a tank with other small, friendly and non-aggressive aquatic species. They are shy and timid fish, so make sure to provide many hiding places like driftwood, rocks, and live plants for your cories.
Cichlids are one of the most diverse families of freshwater fish, including more than 1,300 species of fish with new species being discovered every year. Cichlids include well-known fish such as angelfish, African cichlids, Jack Dempseys, discus fish, jewelfish, and more.

Can you put Cory Catfish with Cichlids?
Because cichlids generally have aggressive or semi-aggressive natures, they usually aren’t good tank mates for cory catfish. If you want to try getting a cichlid for your corydora’s tank, go with a dwarf cichlid, as they are smaller than regular cichlids and are less likely to become aggressive with your corydoras.
While there have been some reports about cichlids successfully sharing a tank with cory catfish, as a general rule, experts recommend avoiding mixing the species in the same tank.
