All bettas have their own quirks, I'm curious to know yours.
Omicron flares whenever I open my laptop on my desk, in front of his tank. He'll flare at it the entire time I have it open, pacing in the front. I'm guessing the dark cover of the laptop makes it possible for him to see his reflection, like how you can see your reflection on dark wood floors.
He also flared at a clothespin I had in my hand, when I slowly opened and closed it. And he flares at the bettas on the Hikari Betta Gold pellet box.
