Hello everyone. I got my two white's about two months ago and i'm really glad i got them. This website has helped me out a lot, i've been looking through it when i have questions, but this is the first post i've made. I've noticed the two of them are very different. The blue one is short, fat and will eat all of anything and enjoys to come out of the cage. The brown one is long, skinny and a picky eater and hates it when I try to pick him or her up. I've heard one them croaking a few times, but i'm not sure which one, i'm always asleep when it happens. Is it just males that croak? I've heard the only way to tell male from female is the croaking and the size. Are the females fatter, longer, or just all around bigger?
