Corydoras are some of the most popular freshwater catfish in the aquarium hobby, but keeping them successfully involves far more than simply adding a few "bottom cleaners" to your tank.

Art covers the essentials of Corydoras care, including ideal group size, aquarium setup, substrate choice, feeding, water conditions, tankmates, common health concerns and some of the unusual behaviours that often confuse new keepers. You’ll also learn why Corydoras should not be expected to survive on leftovers, why species-specific temperature requirements matter, and what those sudden trips to the surface actually mean.

Whether you keep panda corys, bronze corys, peppered corys, Sterbai corys or another member of the Corydoradinae group, this practical freshwater aquarium care guide will help you create better conditions for healthy, active and confident fish.
