Salamander won't eat :(

[Brennah]

So for about two weeks now, my salamander has refused to eat. When he sees food, he closes his eyes and burrows his head, but other than his refusal to eat, he has remained very active and doesn't seem to have lost any weight. He doesn't seem sick, but I'm worried. Does anyone know what might be going on?

What kind of salamander is it?
