Feed them high-quality nutritional food.
Cory catfish are bottom dwellers and spend most of their time scavenging on the bottom, searching for food.
They feed on food leftovers, decayed plants, and small dead fish from the bottom of the tank.
However, we should not make your cory catfish rely on all this waste and should feed them with high-quality nutritional food.
They are omnivore fish and require both meat and plant-matter food in their daily diet to fulfill their ideal nutritional requirement.
Consider feeding them with bloodworms, tubifex worms, brine shrimp, mosquito larvae, blanched vegetables, boiled peas, sinking flakes and pellets, and bottom feeder tablets.
Also, to make sure that you are not overfeeding them, feed them in a quantity that they can finish eating in one to two minutes.
If they are taking more time to finish their food, you are overfeeding them.

Also, they are schooling fish and should be kept in a group of at least 5-6 of their species.
The substrate, plants, equipment, and other decors will take some space.
