thanks in advance
When you measure a Betta or any fish except Angelfish, you do not include their tails. So in body size only, he's probably just about an inch.
Some fish just don't want to flare and won't ever flare. I have a very passive boy that hates other fish being in his tank but won't flare at them, he'll chase and bite but never flare. I've showed him other males and females and won't flare for either. So you could just have a boy that doesn't want to flare.
Have you tried holding a mirror up to him?
