Rosie throwing hands

So this started about a week ago . Almost every time I walk in the room I catch Rosie just throwing hands. He will throw hands for a long time numerous times day. That’s my concern. I feel it’s way too much & why. (Just started about a week ago) ??? I know it’s a type of mating thing. But there literally nothing there . I have not changed anything I made sure to get the whole enclosure so I don’t get asked about all that stuff. Is it normal for him be doing this constantly. Oh also if u listen closely you can hear it. 😆😆😆😆 Also I’ve noticed a loss of appetite. He eats every day but, not much at all.
