What does it look like when bettas sleep? I just went to check on my betta (I don't usually check at this time and the lights are off during the day) and he was just sitting in a corner, with his mouth slightly below the top of the water.
He wasn't moving at all, even his usually fast moving pectoral fins. I was afraid he was dead so I turned the light off, and he quickly swam to a different spot and stayed there. He seemed to have a slightly cloudy look to his eyes almost as if he was sleepy. If it didn't scare me so much it would have been kinda cute.
I was just wondering if he was just sleeping and I shouldn't be worried, or if this could possible be something a bit more serious.
