First: Jampea dwarfs are alot smaller in size than mainlands, BUT FEMALES CAN REACH 16 foot!
Second: Super Dwarfs stay around 6-8 foot. they are about 1000.00 bucks each, and relatively hard to find CB... adults prefer similar housing to a carpet python, they are somewhat arboreal.
there are a ton of different retic locales so go do research before buying em.
i suggest going to the constrictor forums, i know many knowledgeable retic owners on there
