Definately sounds like his fins would be munched then. Maybe try a more peaceful small tetra? I had mine in with flame tetra...not exactly small but worked fine with my guy

Some shoals of neons are fine with bettas, but the risk of putting them together is that the neons can do serious damage to the betta's fins. My Osiris had his shredded by the neons.
They are fin nippers, despite what some sites, books and shop workers may tell you. Putting them together is a risk.
