What flaring means and when it becomes stressful.
Bettas flare to display, defend territory, or react to reflections and other fish. Brief flaring can be normal, but constant flaring can cause stress.
The betta spreads fins and gill covers to look larger. It is a display behavior, not automatically a problem.
Mirrors, reflections, nearby fish, bright glass, or sudden movement can trigger flaring.
If a betta flares for long periods every day, reduce reflections and give the fish more visual cover.
