I recently ordered a small ally snapper from Dan on Kingsnake. He's all alone in a 40 gallon breeder right now (I took your guys' advice and kept him in a separate tank from my common snapper). He is behaving normally but he has not eaten since arriving... It's been about a week and a half now, should I be worried? I tried feeding him live minnows, a frozen pinkie mouse, and shrimp... What else should I try? He doesn't appear to be hungry or unhappy. Any advice?
