Hey Azooinaz,
what size mouse are you feeding your spotted? Because at six months you should be on to at least large fuzzies or small hoppers by now. The reason I ask is because the spotted in that pic is about the size of a six week old; at least in girth.
And for spottedpythons;
it's great that you are enthusiastic about breeding spotteds but before you go and buy breeding age snakes or six month old snakes don't you think that you should try raising them first?
You should get snakes that are only a few weeks old so that you know how to raise young snakes. If you just jump right in and get sub-adults how will you know how to care for any hatchlings you get if they breed? Don't you think that it will be too-late to be desperatly seeking advice on this forum when your eggs go past the expected hatch date, or an egg gets moldy, or your hatchlings won't take pinkies? I'm not trying to discourage you but I do think that you are rushing into something that you know nothing about, and you said yourself that you don't have much experience with snakes! Just slow down, take a breather, don't try to get eggs before you get snakes, and get some six week old pythons. If the local pet shop doesn't have them (and it's best not to get them there) than the best thing to do is to go to a show. Remember don't try too hard and have fun!
Good luck!
