All I can say is don't make the same mistakes that I did.
Do lots of research first, lots and lots. Have a setup all ready to go before you actually buy one. Make sure the temps and humidity and lighting are perfect. This will give you a better chance of success. I personally if I did it over again would not buy from an expo. But instead get one from a breeder in the US. At an expo you can never be really sure what you are really getting. Looking back I'd much rather have spent the extra money to get one from a breeder than have to assist feed a neonate every feeding time.
