I've heard stories from my friend about "stretching out" males meaning they bred him to 10+ females and had alot of slugs out of the ones past 7-8 like thy ran out of swimmers. I personally will see what the male does if I think he can handle 5-6 females I won't over do it but most males can easily handle 3 even my chocolate started breeding at 350g and bred 6 females and all laid good clutches.
