How To Choose An Aquarium Plant Suitable For Cory Catfish? 

When choosing plants for cory catfish, you need to note some of the following points so that the plants will be useful to Cory.

Cary catfish (Corydoras) prefer plants that they can forage off of and plants that provide hiding places. It could be a bush or a large plant with broad leaves. Corydoras aren’t too picky in terms of their preferences, but some live aquatic plants are more suited to the catfish than others.

To minimize damage, avoid plants that cannot tolerate the water conditions of the cory catfish. When selecting plants for the Cory Catfish tank, it is essential to choose plants that can withstand the alkaline, hard water that this fish is used to. You do not need to worry about them uprooting the plants because they are relatively small-sized, and they will rarely interfere with the anchorage of the plants.
