Hes could still be adjusting...I've heard of bettas taking up to two weeks to settle in, but on average it takes a few days, IME, for a normal betta to settle and begin eating once they're in a nice, heated tank wish clean water.
It can also depend on the condition he was in before, obviously a fish that was in bad condition when you bought him is going to take longer to get accustomed to his surroundings.....
You can try a couple different brands pf pellets, some can just be picky eaters too. ;) Just don't be fooled into getting freeze-dried anything, freeze-dried has very little nutrition and can cause bloating issues even when properly prepared.
Haha, I've been beat to it...xD But, just another thing I thought of....I advise ALWAYS soaking your pellets in at least a little tank water before feeding. It makes it easier for them to eat, and reduces the potential for bloating issues ;)
