Bettas generally flare out their gills to look bigger than they are, with one of two primary goals. First, as a courtship moves ("hey, I'm worth looking at!") or as an aggression/dominance expression in order to intimidate or stake our territory. They may even do it in the absence of other fish, if they are used to being fed by humans and want to get your attention...and your food. It is perfectly normal. It is showing off, probably because it saw it's own reflection or another male, or female, and is "flirting" with her.
