If you forget to feed your Betta for a day or two, don't worry about it! They won't starve or anything like that. As a matter of fact, I know of Bettas who have went healthily a month without food.
I suggest feeding your Betta flakes... they have lots of nutriotions in them and my Bettas really enjoy them. Although they are nutricious, your fish can get swim bladder from sucking in water when eating them. So if you decide to feed your Betta flakes, try to get them to sink.
Pellets are also good, but the good brands are pretty expensive. Try to get them to sink so your fish doesn't get swim bladder by sucking in air when eating them. Some good brands contain just as much nutritions that flakes do.
Bloodworms are something Bettas really enjoy! They are expensive, though. I feed my Bettas some of my salamander's bloodworms every few weeks, and they love it! So if you have the money, you can get some bloodworms as a treat for them. And, if you give them the right amount, they'll last you a very long time! My salamander's bloodworms last at least 2 months, and they eat a whole cube of bloodworms, while bettas only eat a few!
Feed your Betta:
Pellets: 3 pellets two times a day
Flakes: 2 medium sized flakes two times a day
Bloodworms: A few bloodworms twice a day

Good luck and I hope I could help!

Initially, I put in 2 to give the new Betta the idea of where the food was, and when it was showing up. But I had other fish in the tank, and I just fed them all at the same time of day (morning worked best for me.) Fish tend to eat more in the light. So I wouldn't suggest putting the food in before you turn off the lgihts and go to bed. Besides, you want to WATCH!

Ahem. They eat in the light. But you do not want direct sun on your tank. That just causes algae to grow, FAST. And once you have algae, you have a problem. Shudder!
Actually, algae is quite nitriocious to Bettas and they enjoy eating it, too! Although don't let too much grow or let it grow uncontrolably.
