Welcome to the tortoise forum. What sort of tortoise have you? I have 5 Horsefields on a 7ft X 2ft 6" table with a bed enclosure either end. 4 red foots that are quickly growing out of a 5ft x 2ft vivarium with an enclosed ramp. that has sleeping accommodation underneath. I have an egg that Narla one of the horsefields hatched. It is her first time being a mum. Should hatch between 12 and 26 June.
