I LOVE dwarf retics.. will have some someday.
There are several different types.
The Jampea dwarfs are bigger 'dwarfs' they can get up to 15' for females.. males smaller.
Super dwarfs are much smaller, and can breed when they're smaller than a big ball python! I believe 6-8' is normal for them. They are long and skinny, so they don't even look 6'.
There are crosses called superjamps.. I'm not sure on the size for them.
Jampeas usually have silver eyes, and the super dwarfs have orange usually.. at least that is what I have noticed.
I know of tame ones of each type.
