well, i went to a friend who has a 4 foot red tail boa. he needs to get rid of it. he said i can go pick it up tomorrow. ive done the same research as i did with my first ball python. everyone says they have the "potential" to get pretty big. well being 4foot, what size tank should i put him in? i have a spare 55 Gallon, 2x20 gallons, 3x10 gallon tanks laying in my shed. he currently has him in a 20 long and to me he is way to big for it. especially being a species that isnt like the ball python and has to have the snug security in a hide. my other friend has a rtb in a 55Gallon and a few rocks and branch's in there. dont know the size of his tank though. i believe its 55. so 55... yay or nay? id like to know soon so i can start setting it up now and getting temperatures ready. any information helps. sorry for asking but when i got my first snake this site helped very quickly. i just want to know from some experience boa people. i know balls and kingsnakes not boa's.............. yet! thanks for all the info on RTB in advanced
