Betta Fish Won't Eat?

[Jewel]

I have tried pellets which my other betta eats, this one won't eat them. The pet store suggested bloodworms, he wants nothing to do with them and I am getting concerned he hasn't eaten in a few days.
Any suggestions???
he is in a 5 gallon tank, no filter or heater. He is very active.
