When neon tetras might work with bettas and why tank size is the first limit.
Neon tetras are not a good fit for small betta tanks. In larger, mature, planted aquariums they may work with some bettas, but stress and nipping are possible.
Neon tetras are schooling fish and should not be kept as one or two fish in a small betta tank.
A larger planted aquarium gives more swimming room and visual breaks.
The betta may chase tetras, or tetras may nip fins. Either problem means the setup is not working.
