Betta Fish: Help!? Big belly?

I do not know if he is too full or if something is happening. I gave him maybe 3 or 4 pellets today since he’s a bigger boy and he eats about every other day sometimes every 2 and gets blood worm once a week. He also gets crushed freeze dried krill. Could any of this be effecting his tummy? What can I do for him? I plan on getting him frozen blood worms but he has freeze dried right now. Sorry for bad photos, it’s very early in the morning and he gets Frusterated with lights at this time. He just tolerates me getting home from work and turning on my light. I took notice of him sleeping on some stones I put in his tank earlier today which was odd to me because he has lots of leafy plants. Is he just weird? Or is something wrong?
