I've switched foods a couple of times with different bettas. I'll tell you about my experiences...
Our combtail hannibal would only eat freeze dried blood worms when we first got him. This continued for several months. He refused the two types of pellets I offered him and the flakes. I bout these really teeny tiny pellets made by New Life Spectrum. He now eats those with freeze dried/frozen blood worms as as a treat. He has also taken to frozen daphnia.
I have a halfmoon male named Odin. He's a dragon scale and the dragon scales have partially covered his eyes. This makes him partially blind. He was on the tiny NLS pellets that I have Hannibal on. As the dragon scales partially covered his eyes, they became too hard for him to see. I now feed him a bigger bright orange pellet. All I did was started dropping 1-2 in at each feeding. I made sure to clean out any that went uneaten. He quickly switched to the new pellet.
Hannibal took months to start eating a variety of foods where as my Odin took a matter of days. Some fish are more stubborn than others. Just keep offering the new food and making the blood worms more scare. He'll start eating.
