Here's a guide of what I feed my bettas, if that helps...I have 2 different types of pellets (Wardley's and Top Fin - though I reccommend Hikari) along with freeze-dried brine shrimp and bloodworms.
Monday, Wednesday, Friday: Pellet food. I often feed them one of each type twice a day (so 2 Top-Fin, 2 Wardley overall).
Tuesday: I crush the pellets and mix it with a bit of freeze-dried brineshrimp
Thursday: Freeze dried bloodworms! Yummm.
Do pre-soak all pellets and freeze-dried foods before feeding them...and make sure to use their own water!
Frozen foods need to be thawed before fed, obviously.
