Cardinal Tetra

Description

Cardinal Tetra Behavior

They are very peaceful fish, which can get along with basically any other peaceful species. They do best when kept in very large schools, which makes them feel more secure. They can, of course, thrive when being kept in smaller groups of up to 5 fish, but they may feel stressed out and probably pass away quickly.

Cardinal Tetra Tankmates

The Cardinal Tetra is a schooling fish, which feels more at ease when kept in a school of at least 5, but a larger group would always be better. Keeping at least 10 or more of them together will also help boost their coloration. Avoid larger fish that may think of your Cardinal Tetras as food, especially because they are so small. Even other larger Tetras may eat them if they could fit them in their mouth.
