Cory Catfish Diet

To choose the best food for cory catfish (Corydoras), it is important to understand a bit about their feeding habits in the wild.

First of all, cory catfish are native to lots of countries in South America. They tend to be found in warmer than average freshwater pools, and shallow streams or brooks.

They prefer soft water in the wild, with a low pH of under 7, although they are definitely hardy enough to survive a range of water pH levels and hardness levels up to 200 ppm of carbonate.

This versatility and adaptability is part of the reason they have become so popular in the aquarium community.

It is important to realize that cory catfish are bottom feeders. This means they are scavengers who like to stalk the bottom of river beds, keeping away from the larger, predator fish that roam in the bulk of the water above. They will display this same behavior in your tank.

Bottom feeders are instantly recognizable because they have downward facing mouths which helps them to scoop food of the river or tank floor.

Benefits of Sinking Fish Food for Corydoras

This is the reason why it is imperative that you feed these fish sinking pellets. They will not be comfortable rising to the surface to feed, although it has sometimes been observed.

It is important that the pellet are also insoluble and stay intact for a long time, as bottom feeders like catfish tend to be slow eaters compared to the voracious surface dwellers.

Cory catfish are omnivores, which means they will eat a mixture of both plants and animal. In fact, like a lot of fish, the Corydoras is an opportunistic feeder which will eat a lot of what it comes across.

For example, it will happily feast on small shrimp, small crustaceans or any insects that fall to the bottom. This accounts for a lot of the protein in its diet. Any artificial diet needs to provide adequate levels of protein, as this is the fuel which keeps their metabolism running.

Of course, cory catfish tend to be small, only growing to 2 or 3 inches depending on the exact species.

As a result, pellets must be quite small so that they can be digested easily. They are a peaceful fish, and they should definitely be kept away from any larger, aggressive species, which may prey on them.
