crocs are something to do a tonne of research on, even for an "experienced herper". they arent always for everyone. but if you can honestly look at everything can take care of it and say yup, this is for me (including there whole lifespan) then i'd look at some smaller species. dwarfs etc (imo still not exactly a small animal) are discussed on here, if you use the search function on the site, there will be info and links etc.
would also like to see some pics of your snakes, esp. the morelia
