Do betta fish sleep vertically?
“When sleeping, they become still, with their eyes open because of their absence of eyelids. Betta fish may lose their color while sleeping (it’s their natural form of self-defense), and they can sleep in different positions: curled up like a cat, on one side, or even vertically, with the head down.
How can you tell if a betta fish is stressed?
If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress.
Do bettas recognize owner?

Not only that, betta fish will always recognize the person who feeds them, making this one of the easiest ways to bond with your betta.
