These tetras prefer soft water but will tolerate a more neutral water. Serpae tetras are hardy fish but prone to disease if not kept well like any other fish is. They accept a wide variety of foods and are not picky eaters. They do not produce a large amount of waste but need a well maintained and filtered aquarium to do well. However, females are generally plumper in appearance and males slightly more colorful. Females and males are nearly impossible to tell apart. Serpae tetras are fairly under-demanding and breed fairly easily. Because of their aggressive tendencies, I would not recommend them as a first fish. A large tank with plenty of plant cover is best. This can be true but it depends on the size of the tank, fish they are kept with, the number of individuals in their school, stress, and a variety of other factors. Serpae tetras have a reputation for being major fin nippers.
