This thread was started by DamienF, and he already had a 55 gallon tank, and (by the time I read it) he had given one of his BPs to his brother, and wanted to know if he could use the 55 gallon tank for just the one snake, because he didnt want to have to buy all new stuff. I dont see any reason someone cant use a 55 gallon tank as long as you make it into a secure home. I have agreed several times that a large tank is not needed, however you can make it work.
