I have no idea what my betta is doing. I've had him for a week now, and every night he freaks out whenever I turn the lights out. Not his bowl light, my bedroom light. At night I usually keep his bowl light on, but I turn off my bedroom light so I can sleep. The second I turn out the light, my betta goes nuts. He starts frantically swimming around the bowl, and flaring at me. He will look directly at me and flare all of his fins. He acts like he is terrified everytime the lights go out!! I watched him go for 20min last night and then I fell asleep. I have no idea how long he kept that up. He does it every single night.
Is this normal, or is something wrong? I was also wondering how many hours he should have of having his bowl light on and off.
