The biggest thing here is that you have to spend money to make money. If you want to make enough money in breeding geckos to quit your day job, you have to drop a big stack of cash to do so. Same with the BP's for the most part. You can't just have a few pairs of geckos and expect to make a living off them. It takes a lot of money and a lot of time to make enough to live comfortably off of any business venture, no matter if its BP's, geckos, frogs, whatever it may be.
