To fix this problem, make sure your tank water is clean and water parameters are right for neon tetras.
Also, make sure the tank is not overcrowded. If neon tetras feel that they are not getting enough room, they might attempt to escape the tank by jumping out.

Neon tetras are nano fish which means a grown neon tetra is about 1.5 inches long. Any large predatory fish in your aquarium can easily eat the neon tetras.
