Joe,
Actually, the most popular misconception about Gabbies is they look very calm and complacent. The truth is that Gabbies will just sit and do nothing, and then WHACK! It happens so fast that the naked eye doesnt even see it coming. I have 15 Gabbies right now, and all of them hiss like hell, but when you introduce food they just sit there. The strike happens so fast all you see is the rat hanging from their mouth. They can strike in any direction including backwards with almost 100% accuracy. They are definitly not for beginers, and even some very experienced keepers dont work with them. Gabby/Rhino crosses are nice, but a bit expensive for a natural occuring interbreed. As far as beginner hots go, I cant really say their is one. They are all different in the way they are kept, and attitudes vary. My first hot was a mangrove snake when I was 15, then bush vipers and gabbies. I only started working with cobras when I felt that I was ready. No 2 snakes even of the same species are the same. Not much different than humans. If you are looking to get into hots, learn as much as you can about what you want to keep, then try and get somone to teach you how to work with them. Its better to know what you want then it is to go through different species and do trial an error. If you ever need any info on anything in particular let me know. I will be more than happy to help you any way I can.
Talk soon,
Chris
