OK..maybe they have changed their betta pellets. They need to be really tiny. The Aqueon pellets I've seen are instead of a tiny round pellet, a sort of tubular shape and some of them are 3x the size of one Hikari pellet. 3 Hikari pellets together are about the size of a bettas eye..which is the amount you want to feed. If in doubt, I recommend you soak them a bit before feeding.
I re-read and had missed before you said his belly was bloated. I would feed pea today and if it he still doesn't look better, fast for a couple days. Let us know if his body starts to curl up at all or he's swimming funny.
