I tried to put caveman in a little box with a frozen pinky but it still wont eat, and he wont drink intill I put him in water and he has a nice water bowl. The store owner said that I have to big of a tank for him and that he was in a ten gallon tank there and now I have him in a 30 gallon. I tried to put the pinky in some chicken broth, butt he still wont eat.Also how do you tell if it's a boy or girl.
