I have a BP right now and im thinking of buying a bigger enclosure for her. So im going to have a 20L open. I was wondering how long it will take for a red tail to outgrow that size enclosure? I really would like to have one bc they are awsome looking. When fully grown what would be a good size enclosure bc i know they get to 6+ feet easily. If you started with a baby and have any help it is greatly appreciated.
