My smallest breeder is 480 g. I didn't think there was any chance of breeding him this year, just because of what I've always read in books and forums. He's my spider and I popped plugs last night. After reading Jas' stories and listening to Reptile radio, I'd give any healthy male with sperm a shot. I'd probably only start with 1-2 females, and give him longer off than an 800 g male, but I don't think that a couple of all nighters would be too dentrimental for a chubby little guy as long as I keep an eye on him. Definately nothing under 80 g though.
