Some are big tetras and small tetras, but generally, they all make decent pets. There are more than 150 different tetra species. They generally all need the same water requirements – pH between 5.5 and 7, and a hardness of 4 kH to 8 kH. They need their water temperatures to be between 70 and 75-degrees Fahrenheit. They do have specific parameters, of course, that you’ve got to keep to. Tetras are a pretty easy species to care for. They may get a little aggressive during feeding time if the aquarium is overstocked, but generally, they’re peaceful fish and won’t bother each other.
