My new male Betta not eating

[gingerbread27]

I just purchased a new male betta last week and he isn't eating, I bought a female at the same time and she is eating. I think he is ok because he is very agressive and is always flaring up at the other males, but is not eating. he is very uniquely colored and I was very lucky to find him, so I want to do what i can for him. He is the prettiest betta I have ever seen, makes my others look just plain. Any ideas on getting him to eat would be appreciated.

Give him a couple days, new bettas tend to be a little pouty at first but usually start eating within about 3 days. You could also try different food types, live food in particular would be very tempting, sometimes they are fixated on one food and will refuse unfamiliar food types.

treat him with some brine shrimp or bloodworms
