I've had over 46 snakes... from green Anacondas to reticulated pythons, snakes were my passion at one point of my life. I think i have been bitten over 100 times, Royal Pythons(ball) are great snakes very nimble and easy to take care of. Once you start getting into more agressive kinds like the African Rock Python(illegal) and the reticulated python then you will have a bit more problems...
Contrary to believes i had 3 anacondas and they were very docile, never got bitten by them. I did get a pretty big scare when my 6ft colombian redtail boa, hit me on the hand and coiled around my neck..lol... but other than that both Boas and pythons are very cool... If you can get your hand on a green tree boa you will love it... they are beautiful...
