Can you add salt in a neon tetra tank?

It is generally not recommended to add salt to a neon tetra tank. Neon tetras are a type of freshwater tropical fish that originate from South America, where the water is generally soft and acidic. Adding salt to the water can alter its chemistry and make it less suitable for neon tetras.

Neon tetras are also very sensitive to changes in water parameters, and adding salt can cause them stress and make them more susceptible to illness. If you are treating a neon tetra for a specific illness, your veterinarian may recommend a specific dosage of salt to add to the water, but otherwise it is best to avoid using salt in a neon tetra tank.

Instead of using salt, you can improve the health and well-being of your neon tetras by providing them with clean, well-filtered water, a varied diet, and a properly heated and lit aquarium.
